All metadata known about a resource is stored in the HTAnchor object. http://www.w3.org/Library/src/HTAnchor.html When a response is received then it parsed by the HTTP response parser and the MIME parser http://www.w3.org/Library/src/WWWHTTP.html http://www.w3.org/Library/src/WWWMIME.html The result is stored in a HTResponse object http://www.w3.org/Library/src/HTResponse.html When the request is terminated, both the request object and the response objects can be destroyed. However, if it is a 2xx code, or a 304 code then the metainformation (length, etags, type, etc.) is stored in a HTAnchor object. The application can query the Anchor object for all the metainformation using the HTAnchor methods. For example, the length is HTAnchor_length(...) Henrik
