Hello Everyone, My Squid Configuration is pretty much default, except the fact, that I have added some refresh_patterns myself and collected from internet in order to get more hits. The server is a Squid3.1.10 (in 3128 intercept transparent) running on Ubuntu 10.10 and comprises of Intel(R) Core(TM) i7 CPU 870 @ 2.93GHz. I would say that everything is fine, except some pages are loading very very slow. For example, www.music.com.bd / www.djmaza.com ... I will try to give more examples as I find more, but for the time being these two sites are very important for my clients. Don't understand actually whats wrong. If this has anything to do with the squid.conf file, I will attach it with the next reply. For the time being here's my refresh_patterns. refresh_pattern ^http://.*\.facebook.com.*\.(jpg|gif|png|swf|wav|3gp|flv|swf|wmv|zip|rar) 10080 300% 40320 reload-into-ims refresh_pattern ^http://.*\.fbcdn.net.*\.(jpg|gif|png|swf|wav|mp3|3gp|flv|swf|wmv|zip|rar) 10080 300% 40320 reload-into-ims refresh_pattern ^http://.*\.yimg.com.*\.(jpg|gif|png|swf|wav|3gp|flv|swf|wmv|zip|rar) 10080 300% 40320 reload-into-ims refresh_pattern ^http://.*\.ytimg.com.*\.(jpg|gif|png|swf|wav|mp3|3gp|flv|swf|wmv|zip|rar) 10080 300% 40320 reload-into-ims refresh_pattern ^http://.*\.gstatic.com.*\.(jpg|gif|png) 10080 300% 40320 reload-into-ims refresh_pattern ^http://.*\.google.com.*\.(jpg|gif|png) 10080 300% 40320 reload-into-ims refresh_pattern dsebd\.org.*\.(jpg|gif|png) 600 50% 3000 refresh_pattern windowsupdate.com/.*\.(cab|exe) 4320 100% 43200 reload-into-ims refresh_pattern download.microsoft.com/.*\.(cab|exe) 4320 100% 43200 reload-into-ims refresh_pattern ^http://.*\.cnn\.com 1000 50% 4320 override-lastmod refresh_pattern ^http://news\.bbc\.co\.uk 1000 50% 4320 override-lastmod refresh_pattern microsoft 1080 150% 10080 override-lastmod refresh_pattern msn\.com 4320 150% 10080 override-lastmod refresh_pattern ^http://.*FIDO 360 1000% 480 refresh_pattern \.r[0-9][0-0]$ 10080 150% 40320 refresh_pattern ^http://.*\.asis$ 1440 50% 20160 refresh_pattern -i \.art$ 10080 150% 43200 refresh_pattern -i \.qtm$ 10080 150% 40320 reload-into-ims refresh_pattern -i \.viv$ 10080 150% 40320 reload-into-ims refresh_pattern -i \.pdf$ 10080 300% 40320 reload-into-ims refresh_pattern -i \.jpg$ 10080 300% 40320 reload-into-ims refresh_pattern -i \.png$ 10080 300% 40320 reload-into-ims refresh_pattern -i \.gif$ 10080 300% 40320 reload-into-ims refresh_pattern -i \.flv$ 10080 300% 40320 reload-into-ims refresh_pattern -i \.ico$ 10080 300% 40320 reload-into-ims refresh_pattern -i \.jpeg$ 10080 300% 40320 reload-into-ims refresh_pattern -i \.x-flv$ 10080 300% 40320 reload-into-ims refresh_pattern -i \.swf$ 10080 300% 40320 reload-into-ims refresh_pattern -i \.wav$ 10080 300% 40320 reload-into-ims refresh_pattern -i \.mp3$ 10080 300% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.mp4$ 10080 300% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.zip$ 10080 300% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.rar$ 10080 300% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.exe$ 10080 300% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.zip$ 10080 300% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.doc$ 10080 300% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.ppt$ 10080 300% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.tiff$ 10080 300% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.ram$ 10080 300% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.rm$ 10080 300% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.rpm$ 10080 300% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.htm$ 1440 50% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.html$ 1440 50% 40320 override-expire override-lastmod reload-into-ims ignore-reload refresh_pattern -i \.txt$ 1440 100% 20160 reload-into-ims override-lastmod refresh_pattern -i \.arj$ 2880 200% 40320 refresh_pattern -i \.Z$ 10080 200% 40320 refresh_pattern ^ftp: 1440 50% 10080 refresh_pattern ^gopher: 1440 10% 1440 refresh_pattern . 0 40% 4320 negative_ttl 1 minute positive_dns_ttl 15 hour negative_dns_ttl 20 second Thanks & Best Regards, Saiful
