Hey, You can use the cache manage interface for this. Take a peek at: http://wiki.squid-cache.org/Features/CacheManager#Cache_manager_Access_Control_in_squid.conf Technically you can run something like: http_proxy=http:///127.0.0.1:3128/ curl -X POST http://cache-peer:3128/squid-internal-mgr/info And see if you get and access denied. If so then it means that your request was answered from the cache_peer. If you need some help with it let me know.

I have a proxy chaining through a tunnel. Every thing works fine !! But in my framework I need to know whether the connectivity is through from squid child to squid parent. What is the best way to know - is there any API or utility that I can use to find it out ? I need to know in both machines that the squid channel is active. Any help in this regard would be appreciated.
