Verify that Squid is Caching Content

You can verify that content is flowing between Endpoint Security, the Caching Proxy and your endpoints by monitoring specific logs and folders.

Check that the Caching Proxy is receiving content from Endpoint Security by monitoring the contents of the cache folder.

1. Log in to the computer running the Caching Proxy.

2. Navigate to: c:\squid\var\

3. Right-click on the cache folder.

4. Click Properties.
   The Properties dialog displays, showing the size of the cache folder.

As endpoints receive new content through the Caching Proxy, the size of this folder increases.

Check that endpoints are connecting to the Caching Proxy by monitoring Squid logs.

1. Log in to the computer running the Caching Proxy.

2. Navigate to: c:\squid\var\log\squid.

3. Open the file access.log.
   The log file displays, showing endpoint connectivity data.

The Squid Log Files topic on the Squid Wiki provides a complete explanation of how to read the Caching Proxy access logs.
