Response Evaluation --
Evaluating the information from a HTTP response
Because HTTP is a protocol based on the Request -
Response scheme, every HTTP request is followed by a HTTP
response. HTTP_Request offers several methods
to evaluate the information from these responses.
A important part of the HTTP response is the response code. The most
well-known response code probably is 404, which
you may have seen in your browser at several occasions. The meaning
of 404 is that the requested ressource could not
be found. A complete list of status codes can be found in RFC 2616.
