I am running ispconfig and lateley i have been seeing the below in the access logs

194.72.238.62 - - [26/Jun/2007:00:41:45 -0500] "\x16\x03" 501 1026 "-" "-"

It looks to me like someone is trying to proxy through my server but I am unsure. How can I stop it or is it normal

Thanks

Looks like normal bots trying to abuse your apache.. Most likely your apache is already patched and protected against such exploits. (Buffer overflow, malformed packages etc)
Normal background noise on the net. Just ignore it for now... worst case simply block IP by firewall.
