Hello Sirs, Operating System : WindowsXP with SP2 Intel 3.0 GHz I have some problem with delay pools partially working in Squid 2.6.STABLE16. I have an acl named STRINGS_SLOW that is meant to slow down access to certain file types which are generally large in size but Squid does not obey the delay parameters as specified by me. This acl has been assigned delay parameter 3 but is taking the download speed of delay parameter 1. All files with extension as listed in STRINGS_SLOW should download at speed of 4000 whereas it downloads at 10000. This was not a problem with Squid 2.6.STABLE13 or 14. Am I wrong somewhere in defining the delay pools? acl STRINGS_SLOW urlpath_regex \.jpeg$ \.jpg$ \.sis$ \.axf$ \.bmp$ \.xls$ \.exe$ \.swf$ \.axf$ \.avi$ \.tar.gz$ \.dat$ \.gz$ \.vbs$ \.iso$ \.mov$ \mp3$ \.mp3$ \.mp4$ \.avi$ \.mpe$ \.mpg$ \.mpeg$ \.asf$ \.wav$ \.ogg$ \.rar$ \.arj$ \.ram$ \.raw$ \.rpm$\.rm$ \.mov$ \.zip$ \.vqf$ \.tar$ \.qt$ \.wav$ acl THIS_SIDE src 192.168.x.x 192.168.x.x 192.168.x.x 192.168.x.x 192.168.x.x acl OTHER_SIDE src 192.168.x.x 192.168.x.x 192.168.x.x 192.168.x.x 192.168.x.x My delay pools: delay_pools 4 delay_class 1 3 echo # pool 1 is a class 2 pool delay_class 2 1 echo # No bandwidth restrictions (acl LOCALUSERS ;local traffic) delay_class 3 3 echo # pool 3 is a class 2 pool of low bandwidth delay_class 4 3 echo # pool 3 is a class 2 pool of low bandwidth delay_access 1 allow THIS_SIDE delay_access 4 allow OTHER_SIDE delay_access 2 allow LOCALUSERS delay_access 3 allow STRINGS_SLOW delay_parameters 1 40000/40000 30000/30000 10000/20000 delay_parameters 2 -1/-1 -1/-1 delay_parameters 3 30000/30000 15000/15000 4000/10000 delay_parameters 4 40000/40000 30000/30000 10000/10000 Best Regards
