303 Status Code Explained
A 303 status code indicates that the response to the request can be found at the specified URL, and should be retrieved from there. It does not mean that something has moved - it is simply specifying the address at which the response to the request can be found.
Why it Occurs
The HTTP status code 303 See Other is the correct manner to in which to redirect web applications to a new URL, particularly after an HTTP POST has been performed.This response indicates that the correct response can be found under a different URL and should be retrieved using a GET method. The specified URL is not a substitute reference for the original resource.
Fixing 303 Error Code
The 303 response MUST NOT be cached, but the response to the second (redirected) request might be cacheable.
The different URL SHOULD be given by the Location field in the response. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URL(s).
