You are not testing the reverse-proxy capabilities. You are testing the
forward-proxy access. You *want* the forward proxy access (aka admin
access) controls to be able to purge and update the cache entries like that.

Remove the -X parameter from your curl command, and run the test from a
separate machine like a real client would be.

If you dont see any change, then you may need to add a bypass (divert
chain rule setting the mark) to the TPROXY rules to prevent it capturing
the port 80 traffic destined directly to the proxies port 80. It should
only be capturing port 80 traffic destined to other servers.
