Proxy Diddling??

Hi Folks,

Anybody else seeing this kind of logged activity?

Requests with error response codes
  GET http://www.diyproxy.com/ap/flag.txt HTTP/1.0 with response code(s) 404 102 responses
  GET http://www.proxygrade.com/proxygrade.php?hash=C59C2E3FD31372BADD1004781F90050A953698723D3E HTTP/1.1 with response code(s) 404 23 responses
  GET http://check.xxx.xxx.xxx.xxx.v.80.pdx8.super.proxy.scanner.ii.9966.org/Provy_OK.html HTTP/1.1 with response code(s) 404 1 responses

I tried turning module proxy_http_module off, but webmail and such stopped working. I feel compelled to restrict proxy services, but don’t want to throw the baby out with the bath water.

So far, it’s only apparent on one of our iworx boxes. Hope it stays that way.

All suggestions are welcome.
