Hello, The following error message appeared when I applied the latest custom_log patch to Squid 2.5 12 Stable: patching file access_log.c patching file cache_cf.c Hunk #2 succeeded at 2627 (offset -6 lines). patching file cf.data.pre patching file client_side.c Hunk #1 succeeded at 868 (offset -3 lines). Hunk #2 succeeded at 889 (offset -3 lines). Hunk #3 succeeded at 910 (offset -3 lines). Hunk #4 FAILED at 2038. Hunk #5 FAILED at 2072. 2 out of 5 hunks FAILED -- saving rejects to file client_side.c.rej patching file icp_v2.c patching file logfile.c patching file protos.h patching file structs.h Hunk #3 succeeded at 623 (offset -1 lines). Hunk #4 succeeded at 1062 (offset -1 lines). Hunk #5 succeeded at 2208 (offset -7 lines). patching file typedefs.h Is this something you can reproduce? The "logformat" works but when I use the acl it doesn't log anything, this is what I use: acl logHTML rep_mime_type text/html logformat combined <standard combined stuff here> access_log /var/log/squid/access.log combined logHTML Thank you, David But just tested this here and rep_mime_type did not work in access_log, never matched anything. This has been corrected in the CVS branch and should get publised as a new patch in a few hours. Please note that the updated patch is relative to current Squid-2.5 (what will become 2.5.STABLE13) and won't apply to 2.5.STABLE12. The fix to the old patch is simply to add the following line http->acl_checklist->reply = http->al.reply; just before the following line in client_side.c: if (!Config.accessList.log || aclCheckFast(Config.accessList.log, http->acl_checklist)) { Regards Henrik
