HTTP status codes are standard response codes provided by website servers on the internet. The codes assist in identifying the cause of the problem when a web page or other resource does not load properly. The term HTTP status code is the common term for the HTTP status line that includes both the HTTP status code and the HTTP reason phrase. HTTP status codes are also known as browser error codes or internet error codes. These are the HTTP status Code Registry’s collected from different sources. This page is formed from HTTP status code information found at ietf.org and Wikipedia.

100 Continue

 Only a part of the request has been received and accepted by the server, if the request has not been rejected, the client should continue with the request.

101 Switching Protocols

The requester has asked the server to switch protocols and the server has allowed to do so.

102 Processing (WebDAV)

A WebDAV request may contain many sub-requests consisting of file operations, requiring a long time to complete the request. This code shows that the server has received and is processing the request, but no response is available yet.
