What does http response code 403 mean?
The 403 Forbidden HTTP status code indicates that the client was able to communicate with the server, but the server doesn’t let the user access what was requested. An example of descriptive English text that can often accompany such a response is You don’t have permission to access /foo on this server. This indicates a fundamental access problem, which may be difficult to resolve, because the HTTP protocol allows the Web server to give this response without providing any reason at all. So the 403 error is equivalent to a blanket ‘NO’ by your Web server – with no further discussion allowed, and according to the RFC specifications, with a 403 error code, the request should not be repeated.
