HTTP Status Codes

  Informational 100 - Continue A status code of 100 indicates that (usually the first) part of a request has been received without any problems and that the rest of the request should now be sent. 101 - Switching Protocols HTTP 1.1 is just one type of protocol for transferring data on the web, and a status code of 101 indicates that the server is changing to the protocol it defines in the "Upgrade" header it returns to the client. For example, when requesting a page, a browser might receive a status code of 101, followed by an "Upgrade" header showing that the server is changing to a different version of HTTP. Successful 200 - OK The 200 status code is by far the most common returned. It means, simply, that the request was received and understood and is being processed. 201 - Created A 201 status code indicates that a request was successful and as a result, a resource has been created (for example a new page). 202 - Accepted The status code 202 indicates that the se...
