The document discusses ASP.NET and provides an overview of how a request moves through the ASP.NET pipeline from IIS to an HTTP handler. It defines key ASP.NET terms and technologies like HTTP modules and handlers. It describes how a page request is processed - from the IIS worker process launching ASP.NET, to the pipeline events firing and determining the correct HTTP handler, to the handler using the page class structure to generate an HTML response.
Meteor is a reactive web application framework that uses JavaScript on both the client and server. It allows for real-time updates as data changes automatically propagate to connected clients without page refresh. The key aspects of Meteor include its reactivity system using Tracker.autorun, the Distributed Data Protocol (DDP) for client-server communication, and Minimongo which mirrors the MongoDB API in the browser for local data caching and manipulation. Meteor applications have a uniform codebase, use reactive templates, publish-subscribe for data synchronization, and allow building isomorphic apps that run on both client and server with shared code.
The document summarizes new features in ASP.NET 4.5 for asynchronous processing of HTTP requests and responses. It introduces the ability to read and write request/response streams asynchronously without blocking threads. It also describes how tasks and async/await keywords simplify asynchronous code. Finally, it discusses new request validation features that allow selectively reading unvalidated request data.
Building RESTful applications using Spring MVCIndicThreads
REST is an alternate and simpler approach for implementing WebServices. It is based on the HTTP protocol and hence leverages a lot of existing infrastructures. It uses an uniform interface thus making it easy to build client applications. In this session we will look at the fundamental concepts behind REST (Resource, URI, Stateless Conversation ..) and how to apply it in the context of a real applcation. We will also discuss the pros & cons of RESTful vs Soap based webservices. We will discuss the design of RESTful application and then look at how to implement it using Spring MVC.

API Design Methodology - Mike Amundsen, Director of API Architecture, API Aca...CA API Management
At some point, we all need to design and implement APIs for the Web. What makes Web APIs different than typical component APIs? How can you leverage the power of the Internet when creating your Web API? What characteristics to many "great" Web APIs share? Is there a consistent process you can use to make sure you design a Web API that best fits your needs both now and in the future?
In this session Mike Amundsen describes a clear methodology for designing Web APIs (based on the book "RESTful Web APIs" by Richardson and Amundsen) that allows you to map key aspects of your business into a usable, scalable, and flexible interface that will reach your goals while creating a compelling API for both server and client developers. Whether you are looking to implement a private, partner, or public API, these principles will help you focus on the right metrics and design goals to create a successful API.
The document discusses the control-view architecture pattern for server-side web programming. Servlets act as controllers that categorize requests and decide which JSP view to forward the request to. Information can be passed from the servlet to the JSP using request attributes. Servlets are classes that contain methods executed by the server in response to requests, rather than generating web pages directly.

ASP.NET Web API is the de facto framework for building HTTP-based services in the .NET ecosystem. With its WCF and MVC lineage, Web API brings to the table better architecture, easier configuration, increased testability, and as always, it's customizable from top to bottom. But to properly use Web API it is not enough to get familiar with its architecture and API, you also need to really understand what HTTP is all about. HTTP is the most common application layer protocol in the world, and yet, not many web developers are familiar with HTTP concepts such as of chunking, caching, and persisted connections. In this full-day tutorial, we will focus on designing and implementing HTTP-based services with ASP.NET Web API, and you will learn how to better use it to implement the features provided by HTTP.
Server-side programming involves writing code that runs on a web server using languages like Java, PHP, and C#. It processes user input, displays pages, structures applications, and interacts with storage. Client-side programming writes code that runs in the user's browser using JavaScript. In a typical interaction, a user's browser requests a page from a server, which processes the request and returns the page which is then rendered in the browser. Common server-side programming languages and frameworks include PHP, Python, and ASP.Net. Web pages can be static with fixed HTML content or dynamic where the content changes based on server-side processing.
This document provides an introduction to ASP.NET, including:
- ASP.NET is a managed framework for building server-side applications using HTTP, HTML, XML and SOAP.
- ASP.NET supports building HTML applications using Web forms, server-side controls and data binding. It also supports non-visual request handlers and Web services.
- ASP.NET improves on the original ASP framework by fully compiling code before execution, not requiring scripting languages, separating code from HTML, and supporting state management in a Web farm.
Handling RESTful API requests with Laravel PHP Framework resource controllers is already very easy. With Laravel 5, handling request routing has been made even easier by using a configuration-as-annotation approach. Controller annotations may take advantage of doc block-style syntax and then be compiled using Laravel's artisan command-line tool. I'll present this approach by providing a few examples and discussing some of the pros and cons.

Web Component Development Using Servlet & JSP Technologies (EE6) - Chapter 4...WebStackAcademy
Setting up a servlet environment
Servlets are Java programs that run on a Web server and build Web pages. Here are a few definitions:
Servlet Development Kits
Java Servlet Development Kit (JSDK) provides Servlet API classes (servlet.jar). Place servlet.jar into CLASSPATH, so that java classes can access it.
Servlet Engines
A servlet is a Java class that needs to be executed in a Java VM by servlet engine. The servlet engine loads the servlet class the first time the servlet is requested. The servlet then stays loaded to handle multiple requests until it is explicitly unloaded or the servlet engine is shut down.
Following are few WebServers that supports servlets:
Apache Tomcat
BEA WebLogic
IBM Websphere
Sun's Java Web Server (JWS)
Apache Tomcat.
Java Servlet Development Kit (JSDK)

SOAP Web Services have a well established role in the enterprise, but aside from the many benefits of the WS-* standards, SOAP and XML also carry additional baggage for developers. Consequently, REST Web Services are gaining tremendous popularity within the developer community. This session will begin by comparing and contrasting the basic concepts of both SOAP and REST Web Services. Building on that foundation, Sam Brannen will show attendees how to implement SOAP-based applications using Spring-WS 2.0. He will then demonstrate how to build a similar REST-ful application using Spring MVC 3.0. The session will conclude with an in-depth look at both server-side and client-side development as well as efficient integration testing of Web Services using the Spring Framework.
This session will provide attendees with hands-on experience and in-depth knowledge of using Node.js as a runtime environment and Express.js as a web framework to build scalable and fast backend systems. Additionally, attendees will learn about Passport.js, a popular authentication middleware for Node.js, and how to use Prisma ORM to handle database operations in a type-safe and efficient manner.
The session will be conducted by experienced developers who have worked with these technologies and will be able to provide valuable insights and best practices. The session will be interactive and include plenty of opportunities for attendees to ask questions and work on real-world projects.

10. Classic ASP Interpreted language Included embedded scripting code mixed into HTML Limited to VBScript Ran in the same process as IIS Inherently not scalable (needed MTS) End of line
12. Walking Upright Designed by Scott Guthrie & Mark Anders Early iteration of ASP.NET Originally known as XSP Not .NET-related – Java based ! Became ASP+ with the design of the CLR Rewritten in C# Renamed when .NET branding introduced End of line
13. What is ASP.NET A framework for developing and delivering information & applications on the web. Known primarily as a page framework. A complete Request/Response management system. Can handle and respond to all sorts of requests on the Internet (or an Intranet). Not a language ! End of line
14. Characteristics of ASP.NET Runs under its own worker process. No longer tied to IIS. Code execution managed by CLR. Code-Behind model allows code separation. Includes state handling facilities. Provides caching functionality. End of line
15. Agenda Defining ASP.NET Terms & Buzzwords A Request-to-Response Walkthrough Additional Technologies Summary
16. Commonly Used Terms Request An HTTP query initiated by a client to a server for the purpose of performing some action. Response A stream of information sent back to a client from the HTTP server that processed the client’s request. ASP.NET Pipeline A series of extensible functionality points which continue the process of a request in order to eventually obtain a response. End of line
17. Commonly Used Terms Page Lifecycle Another series of functionality points that form the process of converting an ASPX page to HTML output. The entire page lifecycle occurs between two pipeline points. Control Model The heart of how ASP.NET builds HTML from compiled classes that represent visual components. End of line
18. Commonly Used Terms HTTP Handlers Classes that are the target of HTTP requests. Assigned by file extension & verb. Map to ISAPI Extensions HTTP Modules Classes that inject mode into the pipeline. Map to ISAPI Filters MVC An design pattern that separates the output design from the information that builds it. End of line

20. What Everyone Sees Desktop Browser Web Server (IIS) http://www.microsoft.com/default.aspx Rendered HTML Now the long version… End of line
21. Getting it to .NET (the low level stuff) Web Server (IIS) Web Server (IIS) Kernel Mode Driver:Http API used by IIS http.sys Worker Process(w3wp.exe) – (one per app pool) Worker Process started (one per pool) and if needed, AppDomain is created. aspnet_isapi.dll AppDomain (one per site/VD) Attached to the extension of the request. Unmanaged DLL that loads the CLR and routes requests to the managed runtime classes via COM-compliant interfaces. ISAPIRuntime(ProcessRequest method) HttpRuntime.ProcessRequest Request sent to the ASP.NET runtime for processing. End of line
22. ASP.NET Takes Over HttpRuntime.ProcessRequest Accessible from now until the end of the request processing. Accessible through HttpContext.Current HttpContext created. This serves as an entry point into the request, response, and other accessible variables. Each AppDomain manages multiple instances so they do not conflict with each other (different users or same user with more than one request). An HttpApplication instance is created. HttpApplication This is where it starts to mean something to you, the developer. Init method starts pipeline processing. End of line
23. Entering the Pipeline Pipeline kicked off in the Init method. HttpApplication BeginRequest Performs event processing. AuthenticateRequest / Post AuthorizeRequest / Post Checks hooks from Global.asax class. ResolveRequestCache / Post Checks hooks from external HTTP Modules. MapRequestHandler / Post AcquireRequestState / Post PreRequestHandlerExecute / Post ReleaseRequestState / Post UpdateRequestCache / Post LogRequest / Post EndRequest PreSendRequestHeaders PreSendRequestContent End of line
24. Entering the Pipeline HttpApplication BeginRequest AuthenticateRequest / Post AuthorizeRequest / Post ResolveRequestCache / Post MapRequestHandler / Post AcquireRequestState / Post PreRequestHandlerExecute / Post ReleaseRequestState / Post UpdateRequestCache / Post LogRequest / Post EndRequest PreSendRequestHeaders PreSendRequestContent End of line
25. Pipeline Events of Interest HttpApplication Provide URL-Rewriting functionality. BeginRequest AuthenticateRequest / Post Repopulate HttpContext.Current.User with stored principal. Page authentication occurs here. AuthorizeRequest / Post ResolveRequestCache / Post MapRequestHandler / Post AcquireRequestState / Post PreRequestHandlerExecute / Post Determine whether to use cached response. ReleaseRequestState / Post UpdateRequestCache / Post Any event can be hooked in Global.asax or in an HTTP Module. LogRequest / Post EndRequest PreSendRequestHeaders PreSendRequestContent End of line
26. HTTP Modules Classes that implement IHttpModule. MyModule : IHttpModule Delegate-based Properties in HttpApplication instance can be wired up. Method functionality equivalent to hooking event in Global.asax Event hooks in modules checked during pipeline processing. End of line
27. AuthenticateRequest WindowsAuthenticationModule FormsAuthenticationModule UrlAuthenticationModule FileAuthorizationModule ServiceModel SessionStateModule OutputCacheModule AuthenticateRequest EndRequest AuthorizeRequest AuthorizeRequest PostAuthenticateRequest AcquireRequestState AcquireRequestState ReleaseRequestState EndRequest ASP.NET HTTP Modules of Interest End of line
28. Module Installation Any level in the Config chain You do know what the Config chain is, right? End of line
29. The Process Continues HttpApplication Just before this event: Proper HTTP Handler located based on request’s extension. BeginRequest AuthenticateRequest / Post Handlers provide necessary processing in order to create a response. AuthorizeRequest / Post ResolveRequestCache / Post MapRequestHandler / Post AcquireRequestState / Post PreRequestHandlerExecute / Post ReleaseRequestState / Post UpdateRequestCache / Post LogRequest / Post EndRequest PreSendRequestHeaders PreSendRequestContent End of line
30. HTTP Handlers Classes that implement IHttpHandler. Determines if the handler instance can be reused by another request. MyHandler : IHttpHandler Functionality assigned to this particular handler. Remember the HttpContext contains all accessible variables, including Response. End of line
31. HTTP Handler Factories Can also implement IHttpHandlerFactory. Allows the instantiation of any handler based on specific conditioning scenarios. MyHandlerFactory : IHttpHandlerFactory End of line
32. Characteristics of an HTTP Handler Access to current HttpContext. Request is in there (as is the Response) ! Handlers are wired to extensions (aspx, etc.). Every handler is responsible for what the response is going to be for a request. ASPX requests expect an HTML response. Config requests expect a “forbidden” response. End of line
33. Handler Execution HttpApplication BeginRequest AuthenticateRequest / Post AuthorizeRequest / Post The determined handler is processed between the PreRequestHandlerExecute and PostRequestHandlerExecute. ResolveRequestCache / Post MapRequestHandler / Post AcquireRequestState / Post PreRequestHandlerExecute / Post ReleaseRequestState / Post UpdateRequestCache / Post LogRequest / Post EndRequest PreSendRequestHeaders PreSendRequestContent End of line
34. Handler Installation Handler factory that returns and executes the handler that will convert an ASPX page to HTML output. Any level in the Config chain End of line
35. The PageHandlerFactory Class Implements IHttpHandlerFactory. GetHandler method returns an IHttpHandler in the form of System.Web.UI.Page-derived class hierarchy. Page class implements IHttpHandler. Page class inherits from Control. Control contains events/methods for the “Page Event Lifecycle”. PageHandlerFactory creates a class structure out of your request. End of line
36. Page Class Structure Follows the structure of an ASP.NET Server Control. Referred to as Page-Gen Class. Created by the PageHandlerFactory class Virtual class created from ASPX page. Controls created based on ASPX content. inherits Partial class with control declarations (class name same as code-behind). partials with Code-behind class is other side of partial class. This is why you can tap into events from your code-behind. inherits ProcessRequest method calls lifecycle events in Control. System.Web.UI.Page inherits implements System.Web.UI.Control IHttpHandler End of line
37. Page Class Structure Created by the PageHandlerFactory class Virtual class created from ASPX page. inherits Partial class with control declarations (class name same as code-behind). partials with Code-behind class is other side of partial class. inherits System.Web.UI.Page inherits implements System.Web.UI.Control IHttpHandler End of line
38. Virtual Class Created from ASPX content Determines language to be used to generate page-gen class. Specifies the partial class to serve as the code-behind. Optional: Name of the code-file for Visual Studio. End of line
39. Virtual Class Created from ASPX content LiteralControl Converted to instances of System.Web.UI.LiteralControl that are added to the control tree of this class. Remember, this class will ultimately inherit from System.Web.UI.Control LiteralControl LiteralControl LiteralControl LiteralControl LiteralControl End of line
40. Virtual Class Created from ASPX content LiteralControl LiteralControl Program code directly added to virtual class. LiteralControl LiteralControl LiteralControl LiteralControl LiteralControl End of line
41. Virtual Class Created from ASPX content LiteralControl Converted to instances of the corresponding server control class for each of these control tags, that will be added to the control tree of this class. LiteralControl The Form control instance is placed directly in the control tree of the class being created; while the TextBox and Label controls are added to the control tree of the Form control. LiteralControl LiteralControl LiteralControl LiteralControl LiteralControl End of line
42. Virtual Class Created from ASPX content LiteralControl “asp” tag-prefix located in config file or Register directive. LiteralControl Class with tag name located in appropriate namespace and assembly. LiteralControl LiteralControl LiteralControl LiteralControl LiteralControl End of line
43. Virtual Class Created from ASPX content __PAGE System.Web.UI.Page LiteralControl ctrl0 System.Web.UI.LiteralControl LiteralControl Function Code Remember: this class “ultimately” inherits from System.Web.UI.Page ctrl1 System.Web.UI.LiteralControl form1 System.Web.UI.HtmlControls.HtmlForm LiteralControl ctrl2 System.Web.UI.LiteralControl Control IDs TextBox1 System.Web.UI.WebControls.TextBox LiteralControl ctrl3 System.Web.UI.LiteralControl LiteralControl Label1 System.Web.UI.WebControls.Label ctrl4 System.Web.UI.LiteralControl LiteralControl ctrl5 System.Web.UI.LiteralControl LiteralControl End of line
44. Virtual Class Created from ASPX content LiteralControl LiteralControl This is the next class you’ll see now. LiteralControl LiteralControl LiteralControl LiteralControl LiteralControl End of line
45. Page Class Structure Created by the PageHandlerFactory class Virtual class created from ASPX page. inherits Partial class with control declarations (class name same as code-behind). partials with Code-behind class is other side of partial class. inherits System.Web.UI.Page inherits implements System.Web.UI.Control IHttpHandler End of line
46. Partial Class Base for virtual class and partial to code-behind Notice the name is the same as the page’s code-behind class. End of line
47. Page Class Structure Created by the PageHandlerFactory class Virtual class created from ASPX page. inherits Partial class with control declarations (class name same as code-behind). partials with Code-behind class is other side of partial class. inherits System.Web.UI.Page inherits implements System.Web.UI.Control IHttpHandler End of line
48. Code-Behind Class Other side of the Control Declarations class Inheriting from Page gives you access to a control’s event lifecycle. End of line
49. Page Class Structure Created by the PageHandlerFactory class Virtual class created from ASPX page. Remember, this entire class hierarchy is the handler returned by the PageHandlerFactory class. It is the HttpApplication pipeline that calls ProcessRequest, kicking off the Page Lifecycle. inherits Partial class with control declarations (class name same as code-behind). ProcessRequest comes from here. It is from there that the lifecycle events are called. Events for the lifecycle come from here. partials with Code-behind class is other side of partial class. inherits System.Web.UI.Page inherits implements System.Web.UI.Control IHttpHandler End of line
50. Page (Control) Lifecycle PreInit Init InitComplete CreateChildControls (IsPostBack) LoadViewState/LoadControlState IPostBackDataHandler.LoadPostData PreLoad Load IPostBackDataHandler.RaisePostBackChangedEvent IPostBackEventHandler.RaisePostBackEvent LoadComplete CreateChildControls (!IsPostBack) PreRender DataBind PreRenderComplete SaveViewState/SaveControlState Render Unload Complete List End of line
51. Most Commonly Known Points Postback only Initialize:OnInit method and Init event Begin tracking ViewState:TrackViewState method Load View State:LoadViewState method Load Postback Data:IPostBackDataHandler.LoadPostdata method Load: OnLoad method and Load event Raise Changed Events:IPostBackDataHandler.RaisePostBackChangedEvent method Raise Postback Event:IPostBackEventHandler.RaisePostBackEvent method PreRender:OnPreRender method and PreRender event Save View State:SaveViewState method Render: Render method Unload:OnUnload method and Unload event End of line
52. Control Rendering Activated through the Control class’ Render method. Each control is designed to output something to the response buffer. Most controls output HTML. Some controls contain others in their tree. Control rendering involves recursively rendering child controls. Controls don’t need to output anything ScriptManager End of line
53. Getting a Response “Rendering” uses an HtmlTextWriter stored in the Response object. Response object is part of HttpContext. Writer sent into Render method. After pipeline complete, contents returned up the chain to aspnet_isapi.dllthen http.sys. Results viewed on browser. End of line
54. Getting a Response You can intercept and/or write directly to the response using Response.Write. Remember classic ASP? Response.WriteFile can be used to output binary information. Can change content type for compatibility with any type of file. Inform browser what’s coming. End of line
55. Agenda Defining ASP.NET Terms & Buzzwords A Request-to-Response Walkthrough Additional Technologies Summary
56. Postbacks Invoked by controls on form that trigger the form to “post”. Another HTTP Request, but of a post-type. Certain lifecycle methods only invoked on postback only. In a postback, the Request object’s Form property contains posted data from HTML elements (using their client IDs).
57. Postbacks Postback only Initialize:OnInit method and Init event Begin tracking ViewState:TrackViewState method Load View State:LoadViewState method Load Postback Data:IPostBackDataHandler.LoadPostdata method Load: OnLoad method and Load event Raise Changed Events:IPostBackDataHandler.RaisePostBackChangedEvent method Raise Postback Event:IPostBackEventHandler.RaisePostBackEvent method PreRender:OnPreRender method and PreRender event Save View State:SaveViewState method Render: Render method Unload:OnUnload method and Unload event End of line
58. ASCX User Controls Register directive defines tag prefix and name for user control. src points to an ascx file in the current web application. During parsing, virtual class is built just like a page, except the base is called UserControl. Also, added to Page’s Controls collection. UserControl also inherits from Control but does NOT implement IHttpHandler. Usage in an ASPX page (or another ASCX control) is just like a server control. End of line
59. Master Pages Code-Behind class inherits from MasterPage, which inherits from UserControl. Master directive similar to a Page directive. ASPX page points to a master page file. End of line
60. Master Pages Control that specifies content to be defined in an ASPX page. Control that wraps content. Each Content control corresponds to a ContentPlaceHolder control. End of line
61. Master Pages Web Server (IIS) Desktop Browser Browse to Default.aspx PageHandlerFactory commences building of virtual class. MasterPageFile attribute encountered. Parsing shifts to master page file and code-behind. Control tree build and added to virtual class. Parsing returns to ASPX page and Content controls turned to code. Each Content control added to the Controls collection of corresponding ContentPlaceHolder control. End of line
62. Direct Browsing Note: you cannot browse directly to an ASCX control or a Master page. End of line
64. ASHX Handlers PageHandlerFactory: Parses ASPX file, building virtual class as an HTTP Handler, with ProcessRequest kicking off page lifecycle. SimpleHandlerFactory: Takes this handler code and returns is as HTTP Handler. ProcessRequest called in the pipeline as always. End of line
65. Themes & Skins Contain server control declarations (without IDs) whose properties overwrite those declared on the ASPX page. Control “registration” applies. Either in skin file or in config file. Applied just before Init lifecycle event. Programmatic application MUST be made in PreInit event. Application using Theme attribute occurs last. Application using StyleSheetTheme attribute occurs first. End of line
66. ASP.NET Ajax More interactive model. Uses JavaScript to invoke Ajax requests. Web Service (WCF) technology can be used to handle response. Ships with controls and components that encapsulate functionality. Ajax Control Toolkit – ships separately Community driven and supported Undergoes Microsoft Scrutiny Better user experience. End of line
67. ASP.NET MVC Process nearly identical to conventional ASP.NET. It’s still ASP.NET Uses a URL routing engine to parse URLs and invoke appropriate classes. http://site/controller/action/id Pipeline is intercepted by a module tapping into PostResolveRequestCache event. Request is picked up by another handler for processing. Controller classes are sought out and processed (similar to code-behind classes). Appropriate Views parsed and rendered. End of line
68. Why Custom Modules Background processes URL rewriting or routing Identity persistence for custom providers (or any other kind of persistence) Benchmarking
70. Tips & Tricks Use your own base page to house common functionality. If overriding On{event} methods, remember that the event-wire-up methods in code-behind fire when you call base On{event}. Example: override OnLoad in a base class, Page_Load in code-behind gets called when you call base.OnLoad. Use <page pageBaseType= demo Register your server controls in your Web.Config file. Eliminates repeat registrations in ASPX & ASCX files. Eliminates registrations in Skin files. End of line
71. Tips & Tricks Remove HTTP Modules that you don’t need If file protection necessary, add file extension (ZIP) to registered extensions in IIS. Bring them into the pipeline for protection and controlled exposure. Presentation available on my site. End of line
72. Tips & Tricks Turn ViewState off in controls that don’t need them – especially grids. In 4.0 the model can be reversed. More compact in 4.0. Override LoadPageStateFromPersistenceMedium & SavePageStateToPersistenceMedium to alter where and how ViewState is saved.
73. Tips & Tricks Deployment Mode In <system.web> <deployment retail=“true” /> Turns debugging, tracing, and detailed errors OFF Machine.Config ONLY Way Advanced PageParserFilter abstract base class Lets you govern the behavior of the ASP.NET Page Parser
74. Agenda Defining ASP.NET Terms & Buzzwords A Request-to-Response Walkthrough Additional Technologies Summary
75. What To Take Away From This ASP.NET does much more than serve pages. Decoupled architecture allows flexible hosting. Pipeline and Event cycle – two different things. Extensible architecture allows opportunities for interception and alteration. Module and Handler model enforce encapsulation and reusability. Be mindful of how much is happenning behind the scenes.
