Hi all, I request that please read my squid.conf file and guide me on the order of the directives and any issue as i am unable to cache a single thing. Does it matter the order of definition of the following? 1. storeurl program 2. refresh patterns 3 storeurl rewrite lists... I assume : 1. whenever a user open a page in his user agent squid very first of all check the refresh pattern for deciding whether to search in the cache or go to web. Am i right? 2. Now if the request match the storeurl rewrite lists then the request is forwarded to storeurl program who then see that if the object is available in the cache in that case it is returned. Otherwise object is fetched from the web and stored as store_url for future reference. Please guide i am totally unclear? 3. With the following squid.conf not a single object is being cached. I am not sure whats happening? ---------------------------------------------------------------------------------------------------- # This is the configuration file for instance 2 which is doing all the caching. squid v 2.7 stable 9 is chosen for its store_url feature. visible_hostname squidlhr1 unique_hostname squidlhr1cache cache_effective_user proxy # Directives to enhance security..... allow_underscore off httpd_suppress_version_string on forwarded_for off log_mime_hdrs on pid_filename /var/run/inst2squid.pid access_log /var/logs/inst2access.log squid cache_log /var/logs/inst2cache.log cache_store_log /var/logs/inst2store.log http_port 1975 icp_port 0 # This option must be supported through giving at compilation snmp_port 7172 #Explicit definition of all is must in squid 2.7 version acl all src all acl manager proto cache_object acl localhost src 127.0.0.1/32 acl to_localhost dst 127.0.0.0/8 acl CONNECT method CONNECT # Only allow cachemgr access from localhost http_access allow manager localhost http_access deny manager # If peering with ISA then following two directives will be required.
