Common Server Errors and Messages
By Lisa Hui
I find it seriously frustrating when servers return cryptic error pages.
If you've ever seen a 403, 404 or 500 message, you know what I mean. Well
sort of, maybe... What you might not know is that all these messages, and
more are called Server Response Codes. Whenever you contact the server and
request a page or execute a CGI script (through your browser), a server will
process this request and respond with these codes, that signal certain things:
||The request was received and is being processed.
||Request processed successfully.
||Request was not processed successfully and redirection in process.
||There was a problem with the request.
||There was a problem with the server itself when trying processing and
carrying out the request.
Some of the more common ones:
401 - Authorization Required
You probably failed to provide the correct access information - usually through
403 - Forbidden
You are not allowed to view the contents of a certain directory either because
the directory was not marked readable and "executable" or the page you were
accessing (the index page when you tried to access the directory) did not
exist and the server will not display the contents of the directory instead.
404 - Not Found
You tried to access a page that was not on the server (occasionally
interchangeable with 403). Either that, or you typed in the URL incorrectly
so the page in question could not be located.
500 - Server Error
You probably tried to access a program or script that executes on the server
and there was a "compilation" or some other run-time problem with the script.
Also happens sometimes when a request to execute a program on the server
