There's also a commonly used http protocol in which the client adds an "If-Modified-Since" header to the get request, and the server either responds with a page if the since date is older than what the server has available, or a response indicating that it doesn't. It's not uncommon for poorly written server code to get this protocol wrong. -- Rick DeNatale Visit the Project Mercury Wiki Site http://www.mercuryspacecraft.com/ -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/
