My squid is using a parent cache including the option prefer_direct. However I do not want squid to send requests in the form http://n.n.n.n/ to the parent where 'n' is a number. I am setting up an acl in the form of
acl by_ip url_regex http://[\d,.]\{8,15\}/ cache_peer my_parent_cache parent 3128 3130 prefer_direct cache_peer_access my_parent_cache deny by_ip cache_peer_access my_parent_cache allow all
before i change the squid configuration I need to make sure about two things. First does the regex look OK? I have read the meta character \{i,j\} may not be supported by all applications. Is it supported by squid-2.4 in linux platform?
The other question I have is that the above block of acl can be placed anywhere in squid.conf?
