Hi, from what I have seen, with v3.3.8, PURGE method is not purging if memory_cache_shared is on. posting in pastebin 2 logs with the same requests debug log with 1 worker / memory_cache_shared on : cache.log is here : http://pastebin.archlinux.fr/467269 corresponding to these requests : 1375190125.156 12 ::1 TCP_MISS/200 1295 GET http://bofip.impots.gouv.fr/bofip/1-PGP.html - FIRSTUP_PARENT/10.154.61.1 text/html 1.1 30/Jul/2013:15:15:25 +0200 "-" "Wget/1.14 (linux-gnu)" 1375190127.367 2 ::1 TCP_MISS/200 255 PURGE http://bofip.impots.gouv.fr/bofip/1-PGP.html - HIER_NONE/- - 1.0 30/Jul/2013:15:15:27 +0200 "-" "squidclient/3.3.8" 1375190130.735 2 ::1 TCP_MEM_HIT/200 1390 GET http://bofip.impots.gouv.fr/bofip/1-PGP.html - HIER_NONE/- text/html 1.1 30/Jul/2013:15:15:30 +0200 "-" "Wget/1.14 (linux-gnu)" this is wrong, because the purge request should have cleared the object from the cache, so the last GET should be a MISS, but it is a HIT Now the same with memory_cache_shared off : cache.log http://pastebin.archlinux.fr/467270 corresponding to these requests : 1375190414.749 14 ::1 TCP_MISS/200 1295 GET http://bofip.impots.gouv.fr/bofip/1-PGP.html - FIRSTUP_PARENT/10.154.61.1 text/html 1.1 30/Jul/2013:15:20:14 +0200 "-" "Wget/1.14 (linux-gnu)" 1375190417.550 3 ::1 TCP_MISS/200 255 PURGE http://bofip.impots.gouv.fr/bofip/1-PGP.html - HIER_NONE/- - 1.0 30/Jul/2013:15:20:17 +0200 "-" "squidclient/3.3.8" 1375190420.694 15 ::1 TCP_MISS/200 1295 GET http://bofip.impots.gouv.fr/bofip/1-PGP.html - FIRSTUP_PARENT/10.154.61.1 text/html 1.1 30/Jul/2013:15:20:20 +0200 "-" "Wget/1.14 (linux-gnu)" this is right, because the purge request have cleared the object from the cache, so the last GET is a MISS. Guess I should file a bug on this. Regards Alex
