Yes, but depending on the version of the proxy server software, this information may be in different places. Here are the possibilities: - "Via:" header (HTTP/1.1) - "Forwarded:" header (some HTTP/1.0 implementations) - "User-Agent: ... via <proxy-software>" (CERN proxy) Cheers, -- Ari Luotonen, Mail-Stop MV-061 Opinions my own, not Netscape's.
