Dear All, I require your help and guidance regarding dynamic content caching. Following are the quries. 1. I am running squid in multiple instances mode (For Cache Disk Failure Protection). I dont think that it has any effect on internet object caching? I am confused that if connect methods are to be duplicate on both of the instances or i have configured it right specially in perspective of windows update. 2. As rewrite_url is not exported in new versions(version 3 and above) of squid is it still possible for squid to cache facebook/youtube videos? Have i configured it correctly? As i have seen no TCP_HIT for mp3,mp4 etc so i think caching is not done. 3. Please can u please check my configuration for windows updates? is there anything else which i have missed there? How could i assure that windows update is being cached properly? Through studying online tutorials mailarchive support and best of my understanding i have configured squid as follows. Please peruse and guide. -------------------------- Squid Cache Instance: visible_hostname squidlhr.v.local unique_hostname squidcacheinstance pid_filename /var/run/squidcache.pid cache_dir aufs /cachedisk1/var/spool/squid 50000 128 256 coredump_dir /cachedisk1/var/spool/squid cache_swap_low 75 cache_mem 1000 MB range_offset_limit -1 maximum_object_size 4096 MB minimum_object_size 10 KB quick_abort_min -1 cache_replacement_policy heap refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern . 0 20% 4320 #specific for youtube belowone.... refresh_pattern (get_video\?|videoplayback\?|videodownload\?) 5259487 99999999% 5259487 # For any dynamic content caching. refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 -------------------------------------------------- Squid Main Instance: visible_hostname squidlhr unique_hostname squidmain cache_peer 127.0.0.1 parent 3128 0 default no-digest no-query prefer_direct off cache_dir aufs /var/spool/squid 10000 16 256 coredump_dir /var/spool/squid cache_swap_low 75 cache_replacement_policy lru refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern . 0 20% 4320 #Defining & allowing ports section.... acl SSL_ports port 443 # https acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT # Only allow cachemgr access from localhost http_access allow manager localhost http_access deny manager # Deny request to unknown ports http_access deny !Safe_ports # Deny request to other than SSL ports http_access deny CONNECT !SSL_ports #Allow access from localhost http_access allow localhost # Windows Update Section... acl windowsupdate dstdomain windowsupdate.microsoft.com acl windowsupdate dstdomain .update.microsoft.com acl windowsupdate dstdomain download.windowsupdate.com acl windowsupdate dstdomain redir.metaservices.microsoft.com acl windowsupdate dstdomain images.metaservices.microsoft.com acl windowsupdate dstdomain c.microsoft.com acl windowsupdate dstdomain www.download.windowsupdate.com acl windowsupdate dstdomain wustat.windows.com acl windowsupdate dstdomain crl.microsoft.com acl windowsupdate dstdomain sls.microsoft.com acl windowsupdate dstdomain productactivation.one.microsoft.com acl windowsupdate dstdomain ntservicepack.microsoft.com acl wuCONNECT dstdomain www.update.microsoft.com acl wuCONNECT dstdomain sls.microsoft.com http_access allow CONNECT wuCONNECT all http_access allow windowsupdate all regards & thanks Bilal _________________________________________________________________ Hotmail: Free, trusted and rich email service. https://signup.live.com/signup.aspx?id=60969
