Connection without response the request has already been

Connection Persistent Connections: Persistent Connection is called Http keep alive and http connection reuse. under http 1. 0, conection not cosidered as  Connection Persistent Connections. so for Persistent Connections client side keep alive heade  added and also at server side when respone is  created keep alive header  added.   http 1. 1 defaults to the use of persistent connections allowing multiple requests and responses to be carried over a single connection.

Keepalive is difficult for the client to determine where one response ends and the next response begins during pipelined HTTP operation.   This is a  problem when Content Length cannot be used due to streaming.    To solve this problem HTTP 1. 1 have a chunked transfer coding that defines a last-chunk bit.

advantages: HTTP requests and responses can be pipelined on a connection. Pipelining allows clients to make multiplerequests without waiting for response allowing a single  connection to be used much moreefficiently, with  lower elapsed time. HTTP Error CodesThe status code of HTTP is one type of integer code. Which is three-digit code, indicates the result code of request. From the first digit of status code we can identify the class of response from. For example, if a status code 200 found on client machine, then it means that this status code is from the 2xx class which indicates the client request was successfully received, understood and accepted.

Different classes of status code are listed below: 1)1xx: InformationThis response indicates that the request has been received and process is under progress. 1)100 continue: The status code 100(Continue) indicates that the initial part of the request has not yet been rejected from the server and the server will send the final response to the client after the request has been fully received.

The server must send  final response after the request has been completed. 2)101 SWITCHING PROTOCOLS: he status code 101(Switching Protocol) indicates that the client has request to the server to switch the protocols and the server machine has accepted to do that.
