▪︎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.
Purpose of HTTP:
▪︎HTTP was invented alongside HTML to create the first interactive, text-based web browser: the original World Wide Web.
▪︎Today, the protocol remains one of the primary means of using the Internet.
Working:
A▪︎s a request-response protocol, HTTP gives users a way to interact with web resources such as HTML files by transmitting hypertext messages between clients and servers.
▪︎HTTP clients generally use Transmission Control Protocol (TCP) connections to communicate with servers.
HTTP utilizes specific request methods in order to perform various tasks:
▪︎GET requests a specific resource in its entirety
▪︎HEAD requests a specific resource without the body content.
▪︎DELETE gets rid of a specified resource
▪︎TRACE shows users any changes or additions made to a web resource
▪︎OPTIONS shows users which HTTP methods are available for a specific URL
▪︎CONNECT converts the request connection to a transparent TCP/IP tunnel.
Advantages:
▪︎It offers lower CPU and memory usage due to less simultaneous connections.
▪︎It reports errors without closing the TCP connection.
Disadvantages:
▪︎It can be used for point to point connection.
▪︎It is not optimized for mobile.
▪︎It does not have push capabilities.
▪︎It is too verbose.
