I have a virtual proxy client and I have a squid proxy server. I would like to add some addresses to block caching for them. Either their domain or IP address:

www.apache.org
188.184.21.108

root@SERVER:/etc/squid # cat /etc/squid/acls/dst_nocache.acl
www.apache.org
188.184.21.108

I added them to the list for non-cache, but it still caches. I check from here:

root@SERVER:/etc/squid # tail -f /var/log/squid/access.log

How can I do this, please? Thanks.

I found the answer. I just needed to understand more about Squid Caching Proxy Access.log.

  • "TCP_" refers to requests on the HTTP port (3128)

  • TCP_HIT A valid copy of the requested object was in the cache.

  • TCP_MISS The requested object was not in the cache.

  • TCP_REFRESH_HIT An expired copy of the requested object was in the cache. Squid made an If-Modified-Since request and the response was "Not Modified."

  • TCP_REFRESH_FAIL_HIT An expired copy of the requested object was in the cache. Squid attempted to make an If-Modified-Since request, but it failed. The old (stale) object was delivered to the client.

  • TCP_REFRESH_MISS An expired copy of the requested object was in the cache. Squid made an If-Modified-Since request and received a new, different object.

    TCP_CLIENT_REFRESH The client issued a request with the "no-cache" pragma. ("reload" - handled as MISS)

    TCP_IMS_HIT An If-Modified-Since GET request was received from the client. A valid copy of the object was in the cache (fresh).

    TCP_IMS_MISS An If-Modified-Since GET request was received from the client. The requested object was not in the cache (stale).

    TCP_SWAPFAIL The object was believed to be in the cache, but could not be accessed.

    TCP_DENIED Access was denied for this request.
