The Request Message mainly consists of a request line, a header, and a body sometimes. The format of the request and the response message is similar.

As we have already told you that the browser acts as the HTTP client and this client mainly communicates with the webserver that is hosting the website. The HTTP makes use of Client-server architecture. This protocol is used to transfer the data in the form of plain text, hypertext, audio as well as video, and so on.In HTTP, the client initializes the transaction by sending a request message, and the server replies by sending a response. The HTTP mainly uses the services of the TCP on the well-known port that is port 80. But there is a difference unlike SMTP, the HTTP messages are not destined to be read by humans as they are read and interpreted by HTPP Client(that is browser) and HTTP server.Īlso, SMTP messages are stored and then forwarded while the HTTP messages are delivered immediately. The HTTP is like SMTP because the transfer of data between the client and server simply looks like SMTP messages.

In HTTP, there is no separate control connection, as only data is transferred between the client and the server. The HTTP is similar to FTP because HTTP is used to transfer the files and it mainly uses the services of TCP.Īlso, HTTP is much simpler than FTP because there is only one TCP connection.

HTTP is one of the protocols used at the Application Layer. HTTP stands for Hypertext Transfer Protocol and is mainly used to access the data on the world wide web i.e ( In this tutorial, we will be covering the HTTP that is the protocol in the Application layer of the OSI Model.
