Hello, I have a question regarding the ICAP-client of Squid (3.0PRE5 and following), I hope this is the right place to ask: Currently I am writing an ICAP-server. What I need now is the authenticated username. The rest of the message describes my tries to get this working and my question. First I implemented http://www.i-cap.org/spec/draft-stecher-icap-subid-00.txt by sending X-Include: X-Authenticated-User in my OPTIONS response. (I don't know if this draft is really implemented, but after a little googlin, I tought so ... Please tell me whether it is implemented in the actual 3.0 or not.) Squid didn't send me the desired header field (X-Authenticated-User) in the next requests. Any mistake by me so far? OK, after that i enabled icap_send_client_username in squid.conf (The only thing I need is in fact the username, I don't care about auth-schemes). This worked at least for REQMOD requests. But in RESPMOD requests the username is still missing. So my big question is: What can I do (or what is the right way) to get the username in REQMOD AND IN RESPMOD requests? I am curious about your answers! best regards Stefan Bischof
