The ASP.NET page life cycle involves 7 stages that occur each time a page is requested:
1. Instantiation - The class representing the ASP.NET page is instantiated and the control hierarchy is initialized.
2. Load view state - Previously saved view state is loaded to restore control values from a previous request.
3. Load postback data - If posted back, data entered by the user is loaded to update control values.
4. Load - The view state and postback data have been loaded to the controls.
5. Raise postback events - Events like button clicks that occurred since the last request are fired.
6. Save view state - The current state of the

ASP.NET 03 - Working With Web Server ControlsRandy Connolly
This document provides an overview of the different types of server controls in ASP.NET, including their common properties, methods, and events. It describes HTML server controls, web server controls, validation controls, user controls, and custom server controls. It also discusses some common properties like ID, width and font that are shared across most server controls, and how to programmatically manipulate properties and handle events.
Web controls are used to build the graphical user interface of ASP.NET applications. There are four main types of web controls: intrinsic controls, list controls, rich controls, and validation controls. Intrinsic controls correspond directly to basic HTML elements like text boxes and buttons. List controls handle repetitive elements like drop-down lists and checkboxes. Rich controls provide advanced functionality like calendars. Validation controls validate user input on the client-side before form submission.

ASP.NET is a web development platform provided by Microsoft that is used for creating web-based applications. It allows applications to be written in languages like C#, VB.Net, and J#. ASP.NET uses a request-response model where requests are handled by the web server which returns responses to the client. It has a set of standard class libraries, the most used being the Web library which contains components for developing web applications. ASP.NET applications go through a page lifecycle on each request, initializing objects and allowing events to be handled at each stage before a response is returned.

2) Creating an associated server control that emits the required JavaScript to register and initialize the client component.
3) Wiring up the server control to load and instantiate the client component code.
AJAX allows web pages to be updated asynchronously by exchanging small amounts of data in the background without reloading the entire page. It uses a combination of technologies including JavaScript, XMLHttpRequest object, and DOM manipulation to update parts of a web page. Common applications that use AJAX include Google Maps, Gmail, YouTube, and Facebook. AJAX provides benefits like creating rich web applications that work like desktop apps and allowing pages to update dynamically without reloading.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Essentials of Automations: The Art of Triggers and Actions in FME
Asp.Net Page Life
1. The ASP.NET Page Life Cycle
Each time a request arrives at a Web server for an ASP.NET Web page, the first thing the Web
server does is hand off the request to the ASP.NET engine. The ASP.NET engine then takes the
request through a pipeline composed of numerous stages, which includes verifying file access rights
for the ASP.NET Web page, resurrecting the user's session state, and so on. At the end of the
pipeline, a class corresponding to the requested ASP.NET Web page is instantiated and the
ProcessRequest() method is invoked (see Figure 1).
[
Figure 1. ASP.NET Page Handling
This life cycle of the ASP.NET page starts with a call to the ProcessRequest() method. This
method begins by initializing the page's control hierarchy. Next, the page and its server controls
proceed lock-step through various phases that are essential to executing an ASP.NET Web page.
These steps include managing view state, handling postback events, and rendering the page's HTML
markup. Figure 2 provides a graphical representation of the ASP.NET page life cycle. The life cycle
ends by handing off the Web page's HTML markup to the Web server, which sends it back to the
client that requested the page.
What is important to realize is that each and every time an ASP.NET Web page is requested it goes
through these same life cycle stages (shown in Figure 2).
Figure 2. Events in the Page Life Cycle
Stage 0 - Instantiation
The life cycle of the ASP.NET page begins with instantiation of the class that represents the
requested ASP.NET Web page, but how is this class created? Where is it stored?
ASP.NET Web pages, as you know, are made up of both an HTML portion and a code portion, with
the HTML portion containing HTML markup and Web control syntax. The ASP.NET engine converts
the HTML portion from its free-form text representation into a series of programmatically-created
Web controls.
When an ASP.NET Web page is visited for the first time after a change has been made to the HTML
markup or Web control syntax in the .aspx page, the ASP.NET engine auto-generates a class. If
you created your ASP.NET Web page using the code-behind technique, this autogenerated class is
derived from the page's associated code-behind class (note that the code-behind class must be
derived itself, either directly or indirectly, from the System.Web.UI.Page class); if you created
your page with an in-line, server-side <script> block, the class derives directly from
System.Web.UI.Page. In either case, this autogenerated class, along with a compiled instance
of the class, is stored in the WINDOWSMicrosoft.NETFrameworkversionTemporary
ASP.NET Files folder, in part so that it doesn't need to be recreated for each page request.
The purpose of this autogenerated class is to programmatically create the page's control hierarchy.
That is, the class is responsible for programmatically creating the Web controls specified in the
page's HTML portion. This is done by translating the Web control syntax—<asp:WebControlName
Prop1="Value1" ... />—into the class's programming language (C# or Microsoft® Visual
Basic® .NET, most typically). In addition to the Web control syntax being converted into the
appropriate code, the HTML markup present in the ASP.NET Web page's HTML portion is translated
to Literal controls.
All ASP.NET server controls can have a parent control, along with a variable number of child
controls. The System.Web.UI.Page class is derived from the base control class
(System.Web.UI.Control), and therefore also can have a set of child controls. The top-level
controls declared in an ASP.NET Web page's HTML portion are the direct children of the
autogenerated Page class. Web controls can also be nested inside one another. For example, most
ASP.NET Web pages contain a single server-side Web Form, with multiple Web controls inside the
Web Form. The Web Form is an HTML control (System.Web.UI.HtmlControls.HtmlForm).
Those Web controls inside the Web Form are children of the Web Form.
2. Since server controls can have children, and each of their children may have children, and so on, a
control and its descendents form a tree of controls. This tree of controls is called the control
hierarchy. The root of the control hierarchy for an ASP.NET Web page is the Page-derived class that
is autogenerated by the ASP.NET engine.
Whew! Those last few paragraphs may have been a bit confusing, as this is not the easiest subject
to discuss or digest. To clear out any potential confusion, let's look at a quick example. Imagine you
have an ASP.NET Web page with the following HTML portion:
Example Code
When this page is first visited, a class will be autogenerated that contains code to programmatically
build up the control hierarchy. The control hierarchy for this example can be seen in Figure 3.
Figure 3. Control Hierarchy for sample page
This control hierarchy is then converted to code that is similar to the following:
Page.Controls.Add( new LiteralControl(@"<html>rn<body>rn
<h1>Welcome to my Homepage!</h1>rn")); HtmlForm Form1 = new
HtmlForm(); Form1.ID = "Form1"; Form1.Method = "post";
Form1.Controls.Add( new LiteralControl("rnWhat is your name?rn"));
TextBox TextBox1 = new TextBox(); TextBox1.ID = "txtName";
Form1.Controls.Add(TextBox1); Form1.Controls.Add( new
LiteralControl("rn<br />What is your gender?rn")); DropDownList
DropDownList1 = new DropDownList(); DropDownList1.ID = "ddlGender";
ListItem ListItem1 = new ListItem(); ListItem1.Selected = true;
ListItem1.Value = "M"; ListItem1.Text = "Male";
DropDownList1.Items.Add(ListItem1); ListItem ListItem2 = new
ListItem(); ListItem2.Value = "F"; ListItem2.Text = "Female";
DropDownList1.Items.Add(ListItem2); ListItem ListItem3 = new
ListItem(); ListItem3.Value = "U"; ListItem3.Text = "Undecided";
DropDownList1.Items.Add(ListItem3); Form1.Controls.Add( new
LiteralControl("rn<br /> rn")); Button Button1 = new Button();
Button1.Text = "Submit!"; Form1.Controls.Add(Button1);
Form1.Controls.Add( new LiteralControl("rn</body>rn</html>"));
Controls.Add(Form1);
To see the full autogenerated code—navigate to the
WINDOWSMicrosoft.NETFrameworkVersionTemporary ASP.NET Files folder and
open one of the .cs or .vb files.
One thing to notice is that, when the control hierarchy is constructed, the properties that are
explicitly set in the declarative syntax of the Web control are assigned in the code. (For example,
the Button Web control has its Text property set to "Submit!" in the declarative syntax –
Text="Submit!" – as well as in the autogenerated class—Button1.Text = "Submit!";.
Stage 1 - Initialization
After the control hierarchy has been built, the Page, along with all of the controls in its control
hierarchy, enter the initialization stage. This stage is marked by having the Page and controls fire
their Init events. At this point in the page life cycle, the control hierarchy has been constructed,
and the Web control properties that are specified in the declarative syntax have been assigned.
We'll look at the initialization stage in more detail later in this article. With regards to view state it is
important for two reasons; first, server controls don't begin tracking view state changes until right
at the end of the initialization stage. Second, when adding dynamic controls that need to utilize view
state, these controls will need to be added during the Page's Init event as opposed to the Load
event, as we'll see shortly.
Stage 2 - Load View State
The load view state stage only happens when the page has been posted back. During this stage, the
3. view state data that had been saved from the previous page visit is loaded and recursively
populated into the control hierarchy of the Page. It is during this stage that the view state is
validated. As we'll discuss later in this article, the view state can become invalid due to a number of
reasons, such as view state tampering, and injecting dynamic controls into the middle of the control
hierarchy.
Stage 3 - Load Postback Data
The load postback data stage also only happens when the page has been posted back. A server
control can indicate that it is interested in examining the posted back data by implementing the
IPostBackDataHandler interface. In this stage in the page life cycle, the Page class
enumerates the posted back form fields, and searches for the corresponding server control. If it
finds the control, it checks to see if the control implements the IPostBackDataHandler
interface. If it does, it hands off the appropriate postback data to the server control by calling the
control's LoadPostData() method. The server control would then update its state based on this
postback data.
To help clarify things, let's look at a simple example. One nice thing about ASP.NET is that the Web
controls in a Web Form remember their values across postback. That is, if you have a TextBox Web
control on a page and the user enters some value into the TextBox and posts back the page, the
TextBox's Text property is automatically updated to the user's entered value. This happens
because the TextBox Web control implements the IPostBackDataHandler interface, and the
Page class hands off the appropriate value to the TextBox class, which then updates its Text
property.
To concretize things, imagine that we have an ASP.NET Web page with a TextBox whose ID
property is set to txtName. When the page is first visited, the following HTML will be rendered for
the TextBox: <input type="text" id="txtName" name="txtName" />. When the user
enters a value into this TextBox (such as, "Hello, World!") and submits the form, the browser will
make a request to the same ASP.NET Web page, passing the form field values back in the HTTP
POST headers. These include the hidden form field values (such as __VIEWSTATE), along with the
value from the txtName TextBox.
When the ASP.NET Web page is posted back in the load postback data stage, the Page class sees
that one of the posted back form fields corresponds to the IPostBackDataHandler interface.
There is such a control in the hierarchy, so the TextBox's LoadPostData() method is invoked,
passing in the value the user entered into the TextBox ("Hello, World!"). The TextBox's
LoadPostData() method simply assigns this passed in value to its Text property.
Notice that in our discussion on the load postback data stage, there was no mention of view state.
You might naturally be wondering, therefore, why I bothered to mention the load postback data
stage in an article about view state. The reason is to note the absence of view state in this stage. It
is a common misconception among developers that view state is somehow responsible for having
TextBoxes, CheckBoxes, DropDownLists, and other Web controls remember their values across
postback. This is not the case, as the values are identified via posted back form field values, and
assigned in the LoadPostData() method for those controls that implement
IPostBackDataHandler.
Stage 4 - Load
This is the stage with which all ASP.NET developers are familiar, as we've all created an event
handler for a page's Load event (Page_Load). When the Load event fires, the view state has been
loaded (from stage 2, Load View State), along with the postback data (from stage 3, Load Postback
Data). If the page has been posted back, when the Load event fires we know that the page has
been restored to its state from the previous page visit.
Stage 5 - Raise Postback Event
Certain server controls raise events with respect to changes that occurred between postbacks. For
example, the DropDownList Web control has a SelectedIndexChanged event, which fires if the
DropDownList's SelectedIndex has changed from the SelectedIndex value in the previous
4. page load. Another example: if the Web Form was posted back due to a Button Web control being
clicked, the Button's Click event is fired during this stage.
There are two flavors of postback events. The first is a changed event. This event fires when some
piece of data is changed between postbacks. An example is the DropDownLists
SelectedIndexChanged event, or the TextBox's TextChanged event. Server controls that
provide changed events must implement the IPostBackDataHandler interface. The other
flavor of postback events is the raised event. These are events that are raised by the server control
for whatever reason the control sees fit. For example, the Button Web control raises the Click
event when it is clicked, and the Calendar control raises the VisibleMonthChanged event when
the user moves to another month. Controls that fire raised events must implement the
IPostBackEventHandler interface.
Since this stage inspects postback data to determine if any events need to be raised, the stage only
occurs when the page has been posted back. As with the load postback data stage, the raise
postback event stage does not use view state information at all. Whether or not an event is raised
depends on the data posted back in the form fields.
Stage 6 - Save View State
In the save view state stage, the Page class constructs the page's view state, which represents the
state that must persist across postbacks. The page accomplishes this by recursively calling the
SaveViewState() method of the controls in its control hierarchy. This combined, saved state is
then serialized into a base-64 encoded string. In stage 7, when the page's Web Form is rendered,
the view state is persisted in the page as a hidden form field.
Stage 7 - Render
In the render stage the HTML that is emitted to the client requesting the page is generated. The
Page class accomplishes this by recursively invoking the RenderControl() method of each of
the controls in its hierarchy.
These seven stages are the most important stages with respect to understanding view state. (Note
that I did omit a couple of stages, such as the PreRender and Unload stages.) As you continue
through the article, keep in mind that every single time an ASP.NET Web page is requested, it
proceeds through these series of stages.
