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 server has received and understood the request, and that it has been accepted for processing, although it may not be processed immediately.
'''203 - Non-Authoritative Information'''
A 203 status code means that the request was received and understood, and that information sent back about the response is from a third party, rather than the original server. This is virtually identical in meaning to a 200 status code.
'''204 - No Content'''
The 204 status code means that the request was received and understood, but that there is no need to send any data back.
'''205 - Reset Content'''
The 205 status code is a request from the server to the client to reset the document from which the original request was sent. For example, if a user fills out a form, and submits it, a status code of 205 means the server is asking the browser to clear the form.
'''206 - Partial Content'''
A status code of 206 is a response to a request for part of a document. This is used by advanced caching tools, when a user agent requests only a small part of a page, and just that section is returned.
