||Standard response for HTTP successful requests.
|301 Moved Permanently
||If the server is set up properly it will automatically redirect the reader to the new location of the file.
||Page has been moved temporarily, and the new URL is available. You should be sent there by the server.
|304 Not Modified
||If the request header includes an 'if modified since' parameter, this code will be returned if the file has not changed since that date. Search engine robots may generate a lot of these.
|400 Bad Request
|| There is a syntax error in the request, and it is denied.
|404 Not Found
||The requested file was not found on the server. Possibly because it was deleted, or never existed before. Often caused by misspellings of URLs.
||The file used to be in this position, but is there no longer.
