The httpd numerical codes returned when your
web browser attempts to access a desired page.
The numerical codes as errors are encountered
directly. The codes are generally recorded in
your own system's access file when someone
accesses any web page on the system.
+ 200 - OK, successful transmission. This is not an error.
+ 302 - Redirection to a new URL. The original page has moved.
This is not an error; most browsers invisibly fetch the new
page upon seeing this result.
+ 304 - Use local copy. This means that the copy of the file on
the web server is not newer than the copy which your web
browser or proxy server has cached locally, so there's no
point in sending the file again. This is not an error.
+ 401 - Unauthorized. The user asked for a document but did not
provide a valid username or password.
+ 403 - Forbidden. Access is explicitly denied to this
(This might happen because the web server doesn't have read
permission for the file you're requesting.)
+ 404 - Not found. This can also be sent if the server has been
told to protect the document by telling unauthorized people
that it doesn't exist.
+ 500 - Server error. Something went wrong with the web server
and it couldn't give you a meaningful response. There is
usually nothing that can be done from the browser end to fix
this error; the server administrator will probably need to
check the server's error log to see what happened.
+ 600 - Error due to network traffic. The connection was not
completed due to load on the network.
