Proxy turn it off

Noticed something funny on my personal webserver. I was testing some proxy settings and left proxy setting on when done. Today morning when I tried to access my server, its unreachable. Checking on the log's there seem to be too many requests proxying through my web server. All the IP's seem to originate from China and destination seems to be Ad server:

Not sure what these requests are but seems like someone is trying to bump their ad revenue. Immediately disabled proxy on my machine.

Lesson to learn: Never forget to turn off proxy settings in Apache.
