I guess that's not bypassable? The ICAP 500 status code does not preclude bypass. In fact, your Squid attempts to bypass this ICAP server error: > 2018/01/29 08:30:01.479 ... bypassing ... exception: Unsupported ICAP status code Unfortunately, Squid bypass code then triggers an internal exception which kills the bypass attempt and ends the HTTP transaction with ICAP_ERR_OTHER: > 2018/01/29 08:30:01.480 ...

Warning: reseting outcome: from ICAP_ECHO to ICAP_ERR_OTHER That second exception looks like a Squid bug to me, but I have not investigated it enough to be sure about that designation (not to mention propose a fix). Your next steps revolve around these standard options: https://wiki.squid-cache.org/SquidFaq/AboutSquid#How_to_add_a_new_Squid_feature.2C_enhance.2C_of_fix_something.3F HTH, Alex. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
