HTTP Proxy -- Is it working?

I have recently installed the Virtual Appliance (Ver. 6.5.417.0) and gone through the instructions for configuring the HTTP Proxy and the appropriate policies.

But I do not see any way of confirming that the setup is working correctly.

How can I confim that the PCs are really getting their signatures and updates from the ERA? What should I see in the log files?

How can I confirm that ERA is really providing signatures and updates from its cache? When I look at IFTOP the cumulative RX value remains a bit higher then the TX value. That seems odd to me. Are there log files that would indicate that it is caching properly?

First of all, Apache HTTP Proxy is a stand-alone product by Apache Software Foundation and there's virtually no correlation to ERA except that it's a part of the All-In-One ERA package.

To list files in the proxy cache, run "htcacheclean -A -p%path%" where %path% is the patch to the cache folder. See https://httpd.apache.org/docs/2.4/programs/htcacheclean.html for available options.

Ok, this is a real help.

"htcacheclean -A -p /var/cache/httpd/proxy/ > proxycachelist.txt" give me a file with over 1000 URLs stored. Probably a good indication that good things are happening.

But how can I find out more? Is there a way to find out what the cache hit ratio is and if so what would be a good ratio?

Please check my older post on this forum. It described how to enable more advanced logging, which can be used to monitor all cache miss and cache hit events.
