I also tried: on_unsupported_protocol tunnel all on Squid v. 4.13. I don't see any denials in the access log. The only thing I see regarding the URL I mentioned earlier is: TCP_MISS/200 673 GET https://ed1lncb62202.webex.com/direct? - ORIGINAL_DST/62.109.225.31 text/html It is easy to reproduce by going to the webex test site: https://www.webex.com/test-meeting.html _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
