purpose of http protocol

HyperText Transfer Protocol (HTTP) is the underlying protocol used by the World Wide Web to define how messages are formatted and transmitted and what actions Web servers and browsers should take in response to various commands. HTTP is designed on Client-server principles which allow a client system for establishing a connection with the server machine for making a request. These links may be in any form like text or images. The most important of these, in my opinion, includes persistent connections, chunked transfer-coding and fine-grained caching headers. HyperText Transfer Protocol is the basic communication protocol used in Internet life. XHR is often used to request and recieve data for the purpose of modifying a web page. Despite the XML and Http in the name, XHR is used with other protocols than HTTP, and the data can be of many different types like HTML, CSS, XML, JSON, and plain text. The XHR Object is … HTTP/1.1 200 OK Date: Mon, 27 Jul 2009 12:28:53 GMT Server: Apache/2.2.14 (Win32) Allow: GET,HEAD,POST,OPTIONS,TRACE Content-Type: httpd/unix-directory TRACE Method. The current version of the protocol is HTTP/1.1, which adds a few extra features to the previous 1.0 version. TCP and the UDP are the main transport protocols which are used in the modern era. Here is a beginners guide to HTTP covering details of what is HTTP, structure of HTTP request and response in a transaction, what is HTTPS, viewing HTTP request and response in Chrome and list of HTTP status codes. 1.1 Purpose The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, collaborative, hypermedia information systems. Any man-in-the-middle can listen to TCP communication and read your personal data transmitted over the web. HTTP is an insecure protocol since data in an HTTP protocol is encoded in plain text format. When you open a web page that uses HTTP, your web browser uses the HyperText Transfer Protocol (over port 80) to request the page from the webserver. We'll briefly touch upon these features in this article; in-depth coverage will be provided in part two. Hyper Text Transfer Protocol (HTTP): HTTP is designed for transferring a hypertext among two or more systems. HTTP has been in use by the World-Wide Web global information initiative since 1990. Most commonly, it is used for … The HTTPS protocol (also called ‘HTTP over SSL’, ‘HTTP Secure’, or ‘HTTP over Transport Layer Security’) is a web communication protocol designed to secure communications over computer networks by encrypting it through SSL/TLS. Clients and servers communicate by exchanging individual messages. It is a request-response protocol in the client-server computing model. What is the purpose of HTTP? HTML tags are used for creating links. It’s a protocol that allows communication between different systems. In other words, HTTP provides a pathway for you to communicate with a web server. HTTP (Hypertext Transfer Protocol) is the set of rules for transferring files, such as text, graphic images, sound, video, and other multimedia files, on the World Wide Web.As soon as a web user opens their web browser, the user is indirectly making use of HTTP.HTTP is an application protocol that runs on top of the TCP/IP suite of protocols (the foundation protocols for the Internet). Network ports, their protocols and purposes. The Hypertext Transfer Protocol is an application protocol for distributed, collaborative, hypermedia information systems that allows users to communicate data on the World Wide Web. The TRACE method is used to echo the contents of an HTTP Request back to the requester which can be used for debugging purpose at the time of development. The first version of HTTP, referred to as HTTP/0.9, was a simple protocol for raw data transfer across the Internet. When the webserver receives and accepts the request, it uses the same protocol to send the page back to you. HTTP stands for hypertext transfer protocol.
