Test: HTTP (Hypertext Transfer Protocol) - Computer Science Engineering (CSE) MCQ

By default the http connection is issued with persistent connection. In persistent connection server leaves connection open after sending response. As little as one RTT (Time for a small packet to travel from client to server and back) is required for all referenced objects.

In first step client sends a segment to establish a connection with the server. In the second the step the client waits for the acknowledgement to be received from the server. After receiving the acknowledgement, the client sends actual data in the third step.

The line followed by request line are called header lines and status line is the initial part of response message.

There are two methods which help to request a response from a server. Those are GET and POST. In GET method, the client requests data from server. In POST method the client submits data to be processed to the server.

The HTTP protocol requests the server of the website its trying to access so that it can store its files, images etc. in cache memory. This request of asking the server for a document considering a specific parameter is called conditional GET Request.

RTT stands for round-trip time.

By default the http connection will be persistent connection. Hence it will take only 1 RTT to fetch a webpage from a server.

It is specified in the method field of request line in the HTTP request message.

HEAD method is much faster than GET method. In HEAD method much smaller amount of data is transferred. The HEAD method asks only for information about a document and not for the document itself.
