File Transfer Protocol
FTP is a standard protocol for transferring files over the Internet. It establishes two connections between hosts - one for data transfer and the other for control information like commands. FTP uses ports 21 for control and 20 for data. It supports different transmission modes like stream, block, and compressed. It allows clients to authenticate, specify file formats, and access files anonymously in some cases.
Http Introduction
HTTP is the most popular application protocol on the internet. It uses the client-server model where an HTTP client sends a request to an HTTP server using a request method like GET or POST. The server then returns a response with a status code and can include a message body. A URL identifies a web resource and includes the protocol, hostname, port, and path. HTTP specifications are maintained by the W3C and the current versions are HTTP/1.0 and HTTP/1.1. The HTTP request and response include a start line, headers, and optional body. Common status codes indicate success, redirection, or client/server errors.
Http Protocol
HTTP (Hypertext Transfer Protocol) is the set of rules for transferring files between clients and servers on the World Wide Web. Communication occurs through HTTP requests from clients to servers and HTTP responses from servers to clients. A typical request/response cycle involves a browser requesting an HTML page from a server, which returns the page, and then the browser requesting and receiving additional files like stylesheets, images, and JavaScript code referenced in the HTML. An example is provided of an HTTP request from a browser to a server for a youtube.html page and the corresponding response.
HyperText Transfer Protocol (HTTP)
HTTP is the application-layer protocol for transmitting hypertext documents across the internet. It works by establishing a TCP connection between an HTTP client, like a web browser, and an HTTP server. The client sends a request to the server using methods like GET or POST. The server responds with a status code and the requested resource. HTTP is stateless, meaning each request is independent and servers do not remember past client interactions. Cookies and caching are techniques used to maintain some state and improve performance.
Hypertext Transfer Protocol
This document provides an overview of the HTTP protocol. It discusses that HTTP has been used by the World Wide Web since 1990 to enable communication between web browsers and servers. It describes some popular web servers like Apache and clients like Firefox. It explains the basic operation of HTTP including requests with methods like GET and responses with status codes. It also discusses URLs, URIs, and different versions of HTTP from 0.9 to 1.1.
Hypertexttransferprotocolhttp 131012171813-phpapp02
HTTP is the foundation of data communication for the World Wide Web. It is a protocol for transferring various forms of data between a client and server. HTTP works by establishing a TCP connection between a client and server, through which HTTP request and response messages are exchanged. These messages include request methods like GET and POST, as well as response status codes like 200 for success and 404 for not found. HTTP is a stateless protocol, but cookies and caching allow servers to identify users and reduce response times.
Hypertext Transfer Protocol
HTTP is the protocol used to retrieve web pages over the Internet. It uses a request/response model where browsers make requests to web servers using HTTP and receive responses. HTTP 1.1 introduced persistent connections allowing multiple requests to be sent over a single TCP connection, improving efficiency over HTTP 1.0 which required a separate connection for each request. Caching of responses in browsers and proxies improves page load times and reduces server load.
HTTP Presentation
HTTP/2 is an updated protocol that improves upon HTTP/1.1 by allowing multiple requests to be sent simultaneously over a single TCP connection using multiplexing and header compression. It reduces latency compared to HTTP/1.1 by fixing the head-of-line blocking problem and prioritizing important requests. Key features of HTTP/2 evolved from the SPDY protocol and include multiplexing, header compression, prioritization, and protocol negotiation.

TFTP - Trivial File Transfer Protocol
Overview of the TFTP protocol.
TFTP (Trivial File Transfer Protocol) is, as its name implies, a very simple mechanism for transferring files between 2 hosts.
TFTP is typically used for downloading software and configuration files to Internet and LAN appliances like routers, switches and gateways.
Due to its simplicity, TFTP is often contained in bootloader programs that need to have a very small memory footprint in order to fit into EEPROM style chips.
TFTP is not a reduced version or predecessor of FTP. TFTP and FTP do not have anything in common and serve different purposes. While FTP comes with some minimal access and session control and other features, TFTP is barely a file transport mechanism.
FTP
FTP uses two TCP connections - a control connection on port 21 for sending commands and a data connection on port 20 for transferring files. The control connection maintains state about the user and session and is used to open and close the data connection for individual file transfers. Common FTP commands are used to login with username and password, list directory contents, and get/put files between hosts.
File transfer protocol
FTP (File Transfer Protocol) is a standard network protocol used to transfer computer files between a client and server over a TCP/IP network. FTP uses TCP/IP to transfer files and allows users to exchange files between accounts, transfer files between accounts and desktop computers, or access online software archives. When transferring files, FTP facilitates either uploading files from a personal computer to a server or downloading files from a server to a personal computer.
Http request&response
The document discusses HTTP requests and responses. It explains that HTTP is the most popular application protocol used on the internet. An HTTP client sends a request to a server, which returns a response. Requests use URLs to identify resources and consist of a request line and optional headers. Responses also include a status line and headers to provide information to the client. HTML forms allow sending request data to servers using GET or POST requests.
HTTP Basics
HTTP is the protocol that powers the web. It uses a request-response model where clients make requests that servers respond to. Common request methods include GET, POST, HEAD, PUT, DELETE, and OPTIONS. Responses include status codes like 200 for OK and content types. HTTP 1.1 added features like persistent connections and chunked encoding. Cookies are used to maintain statelessness. HTTPS uses SSL/TLS to secure HTTP connections with encryption, server authentication, and integrity.
Ftp
File Transfer Protocol (FTP) allows copying files between two hosts over TCP/IP. It establishes two connections - one for control information like commands and responses, and one for transferring files. FTP solves problems like different file naming conventions or data representations between systems. It uses ports 21 for control and 20 for data, and defines attributes like file type, data structure, and transmission mode to handle heterogeneous systems.
Email HTTP And FTP
The birth of electronic mail occurred in 1965 at MIT. Ray Tomlinson sent the first message between two computers in 1971 using the "@" symbol to denote sending from one computer to another. Email was further developed to allow organization into folders and offline reading. Common email protocols include SMTP, POP3, and IMAP. Email is important as it saves time and money while allowing instant communication. HTTPS encrypts messages sent over HTTP for secure transmission. FTP allows two computers to connect over the internet and transfer files by converting them to binary for transmission.
HyperText Transfer Protocol
HTTP (Hypertext Transfer Protocol) is a stateless, request-response protocol for transferring hypermedia documents across the internet. It runs on top of TCP and uses port 80 by default. HTTP specifies the messages that clients and servers can send and the responses received. Common HTTP methods include GET, HEAD, POST, PUT, DELETE, and OPTIONS. Status codes inform the client if the request was successful or not. HTTP headers provide additional metadata in requests and responses.
Web and http computer network
The document provides an overview of the World Wide Web (WWW) and Hypertext Transfer Protocol (HTTP). It discusses the structure of the WWW including clients, servers, caches and components like HTML, URLs, and browsers. HTTP is described as the application protocol that allows for data communication across the internet using requests and responses. Key aspects of HTTP like features, architecture, status codes, and request methods are summarized.
Ftp server
FTP is a common protocol used to transfer files between a client and server. The document discusses configuring an FTP server on Linux using the vsftpd package. Key steps include installing vsftpd, configuring the vsftpd.conf file to enable anonymous downloads and local logins, and testing access locally and remotely using FTP, Telnet, and netstat commands. The document also provides recommendations for security settings like restricting users in ftpusers and enabling TCP Wrappers firewall rules.
File Transfer Protocol
The document discusses the File Transfer Protocol (FTP). FTP uses two channels - a control channel over port 21 to send commands and a data channel over port 20 to transfer files. It describes common FTP commands to connect, navigate directories, set transfer properties, transfer files, and end sessions. The document also covers FTP status codes, transport bindings using active/passive modes, proxy transfers, and security issues like cleartext data transfers that FTP has addressed with TLS encryption.

Here are explanations of the requested concepts:
1. SMTP (Simple Mail Transfer Protocol):
- Used for sending and receiving email messages between servers
- Works on TCP port 25
- Client (email sender) connects to SMTP server and sends the email
- SMTP server then handles delivering the email to recipient's SMTP server
2. POP (Post Office Protocol):
- Used for retrieving email from a remote server to a local machine
- Works on TCP port 110 (POP3)
- User must first authenticate with their username and password
- POP downloads all emails from the server to the local machine
- Emails are then deleted from the server by default

FTP - File Transfer Protocol
Overview of the FTP protocol.
In the early days of the Internet, applications were mostly restricted to mail transfer (email) and file transfer. FTP (File Transfer Protocol) is one of the first standardized protocols for exchanging binary and text files between hosts.
FTP is rather simple in that it uses a TCP connection for exchanging commands and a data transfer TCP connection for the actual file transfer.
In normal FTP operation, the client opens the control connection to the FTP server while it is up to the server to open data connections for each file transfer. With the upcoming firewalls, this scheme proved to pose a problem since firewalls tend to block incoming TCP connections. Thus a passive mode was defined where the client is responsible to open the data connection to the server.

Web Services 2009
Web services allow programs to call methods on other computers over a network. They are frequently web APIs that can be accessed remotely and executed on another system. Web services consist of method information describing the method being called and scoping information describing required arguments. This information is packaged and sent across the network using various protocols like HTTP, SOAP, and XML-RPC. The internet protocol stack, consisting of layers like application, transport, network and link, is used to break information into packets that can travel over the network to their destination and be reassembled.
Web Services 2009
Web services allow programs to communicate over a network by calling methods on remote systems. They are frequently web APIs that can be accessed over a network like the internet. A web service call packages method and scoping information into an envelope that is transported across the network using defined protocols like HTTP and TCP. At the destination, the same protocols unpack the envelope and call the requested method. Web servers store web pages and dynamic content, and respond to client requests over the internet using HTTP to deliver HTML files and other objects.

Tim Berners-Lee outlined the advantages of a hypertext-based, linked information system in March 1989 and named his project "Enquire". By the end of 1990, Berners-Lee and Robert Cailliau created the first Web browsers and servers and designed the first version of HTTP. HTTP sits atop the TCP/IP protocol stack and allows for the delivery of HTTP messages over reliable TCP connections. HTTP requests use methods like GET and POST while responses use status codes to indicate the result.
Http request&response by Vignesh 15 MAR 2014
The document discusses HTTP request and response messages. Some key points:
- HTTP is a stateless, client-server protocol where clients send requests to servers and servers return response messages. Requests use methods like GET and POST and URLs to identify resources.
- Request messages contain a start line with the method, URL, and HTTP version, followed by header lines. Response messages contain a start line with the status code and reason, followed by header lines and an optional body.
- Common status codes include 200 for success, 404 for not found, 401 for unauthorized, and 500 for server errors.
- HTML forms can send data via GET by adding parameters to the URL or POST by placing them in the

Hypertex transfer protocol
The document provides an overview of the Hypertext Transfer Protocol (HTTP) including:
- HTTP is an application-level protocol for distributed, collaborative, hypermedia information systems that facilitates information transfer across the internet.
- A URL uniquely identifies resources over the web and consists of the protocol, hostname, port, and path/file name.
- HTTP uses a request-response model where a client sends a request and the server returns a response. Common request methods are GET, POST, HEAD.
- Responses contain a status line indicating success or error, and headers providing metadata about the response.

Http request&response session 1 - by Vignesh.N
The document discusses HTTP requests and responses. Some key points:
- HTTP is the most common protocol for web communication. A client sends a request to a server, which returns a response. Requests use methods like GET and POST.
- URLs identify web resources and have components for the protocol, hostname, port, and resource path. Default ports include 80 for HTTP and 443 for HTTPS.
- HTTP requests contain a request line with the method, URI, and version. Headers provide additional information. Responses contain a status line and headers to describe the response.
- HTML forms allow sending request data via GET or POST. GET appends data to the URL while POST sends it in the request body.
Httpbasics 1207412539273264-9-converted
HTTP is the protocol that powers the web. It uses a request-response model where clients make requests that are met with responses from servers. Requests use methods like GET and POST and include URIs to identify resources. Responses include status codes like 200 for success and 404 for not found. HTTP is stateless but cookies can provide statefulness. HTTPS adds encryption with SSL/TLS to provide security for HTTP communications.
Under the Covers with the Web
Walks through the basics of the HTTP protocol, URLs, cookies and caching, with tricks and tips that can be used by web developers. From a Geek.class I did on Oct 6, 2011 for Meet the Geeks.
HTTP Protocol Basic
The HTTP protocol is an application-level protocol used for distributed, collaborative, hypermedia information systems. It operates as a request-response protocol between clients and servers, with clients making requests using methods like GET and POST and receiving responses with status codes. Requests and responses are composed of text-based headers and messages to communicate metadata and content. Caching and cookies can be used to improve performance and maintain state in this otherwise stateless protocol.
ASP.NET Web API and HTTP Fundamentals
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.
HTTP / 1, HTTP / 2 and HTTP / 3: Past, present and the future of APIs
The document provides an overview of the history and evolution of HTTP protocols, from versions 0.9 to 3. It discusses key aspects of HTTP/1.1 including resources, client-server architecture, status codes, and REST. HTTP/2 improvements like multiplexing and binary format are covered. Emerging technologies like GRPC, RSocket, and HTTP/3 which uses QUIC are also summarized. The future of application programming interfaces and network communication is moving towards lower latency protocols built on top of HTTP like HTTP/3 that leverage UDP.
Build a Micro HTTP Server for Embedded System
Apache HTTP Server, NGINX .. are famous web servers in the world. More and more web server frameworks come and follow up, like Node.js, Bottle of Python .., etc. All of them make us have the abilities to get or connect to the resources behind the web server. However, considering the limitations and portability, they may not be ported directly to the embedded system which has restricted resources. Therefore, we need to re-implement an HTTP server to fulfill that requirement.
I will introduce how do I use the convenience of Python to implement a Micro HTTP Server prototype according to RFC 2616/HTTP 1.1. Then, re-write the codes in C to build the Micro HTTP Server and do the automated testing with Python Unit Testing Framework. Finally, I combined the Micro HTTP Server with an RTOS and light the LEDs on an STM32F4-Discovery board.
general protocol basics
This document provides an overview of web applications and the HTTP protocol. It describes the evolution of static pages to dynamic web applications. It outlines the tier structure of web applications and covers browsers, servers, server-side and client-side scripts, and databases. The document then details the HTTP protocol, including sessions, URLs, requests, responses, status codes, and cookies. It explains how HTTP establishes and maintains stateless sessions between clients and servers.
