HTTP Status Messages
Forward: HTTP Status Messages explained.

Introduction
Information that goes to-and-fro as described above is possible only if it respects a set of rules called the HTTP protocol. There is software in the Internet that implements the HTTP protocol. So far as you, the client and your browser are concerned, if there is an error in the transmission of information, the software will send the error message to your browser. An error message consists of a number and a short text. Some of the short texts are not explicit, so I will explain the inexplicit ones below. The error messages have been typed in their different categories below (display content as a web page):
| Message: | Description: |
|---|---|
| 100 Continue | Only a part of the request has been received by the server, however as long as it has not been rejected, the client should continue with the request. |
| 101 Switching Protocols | The server switches protocol. |
| Message: | Description: |
|---|---|
| 200 OK | The request is OK |
| 201 Created | The request is complete, and a new resource is created |
| 202 Accepted | The request is accepted for processing, however the processing is not complete |
