Hi, I'm trying to modify logformat to display header of this folowing websites. My purpose is to be able to use the correct pattern for refresh_pattern. Here are my rules acl googlevideo url_regex -i googlevideo\.com acl kaspersky url_regex -i kaspersky\.com acl kaspersky-labs url_regex -i kaspersky-labs\.com acl metacafe url_regex -i metacafe\.com acl apple url_regex -i phobos\.apple\.com acl pornhub url_regex -i pornhub\.com logformat squid %ts.%03tu %6tr %>a %Ss/%03Hs %<st %rm %ru %un %Sh/%<A %mt logformat analisa %{%H:%M:%S}tl %-13>a %-6<st %03Hs %-17Ss %-24mt %-6tr %ru *REQ* *C:%{Cache-Control}>h *P:%"{Pragma}>h *LMS: %"{Last-Modified}>h *REP* *C:%"{Cache-Control}<h *P:%"{Pragma}<h *LMS:%"{Last-Modified}<h *Exp:%"{Expires}<h access_log /var/log/squid/analisa.log analisa googlevideo kaspersky kaspersky-labs metacafe apple pornhub access_log /var/log/squid/access.log squid The rules above did not work. The file analisa.log is empty even after I accessed several websites above. Did I miss something? Any help would be greatly appreciated. Rgds, Zul
