I believe the way to do that is to use the HEAD method in your request, so that the request line will read "HEAD /folder/page.html HTTP/1.1". The response will be all the headers that it would normally send before that document in a GET response, but no document. This is the standard method for verifying links or checking if a document has changed without actually getting that document. I personally am having trouble implimenting the HEAD method, even though the HTTP 1.1 specs, which I am trying to follow, require it. The problem is that my server is designed to generate pages on the fly, and each page, in all likelyhood, will be different every time the client retrieves it. Some pages actually carry out an action, such as move your virtual persona into a new confrencing area, although sensitive actions would be reserved for POST requests. What would be the standard response in this case? Right now, it only responds with 501 Not Implimented.
