the Web server
Bad request 400:
This is a fairly common error and basically means that
the requested document could not be sent because of syntax
error in the URL (site address)
Unauthorised 401:
This is one of the most common error messages and usually
means that the Server is expecting some sort of encryption
id from the browser

The document you are requesting is "forbidden" meaning
that you do not have read privileges or are not allowed
to have the page sent to you

no longer exists or that the URL (site address) is incorrect
Internal Error 500:
The server was unable to send the html document to you
due to an internal (server software) error

This error occurs when for example, you have pressed the
submit button on a form. The server reply's with this
error message because it doesn't support the feature that
you have requested. This is not a real common error, but
typically occurs when new features or forms are implemented
