Hi - I'm having trouble using squid plus a url-rewrite-program as a reverse proxy to a system that requires digest authentication. Digest authentication fails because the uri=<string> in the Authorization header isn't rewritten & so it doesn't match the POST URI created by url-rewrite-program. Is there a way to also rewrite the uri string in the Authorization header before squid sends it to the originserver? If it helps clarify, I'm using curl to POST to squid as a reverse proxy to a custom web server. And, if I eliminate the url-rewrite-program authorization works fine. e.g. [curl] --> POST /myfile.txt --> [squid (url-rewrite myfile.txt to <32-bit hex string>)] --> POST /<32bit-hex-string> --> [originserver] Thanks, Mike
