YMSG: HTTP Tunneling
This signature detects Yahoo Instant Messenger traffic over HTTP. Depending on your corporate policies, Instant Messaging can be a violation of your end-user's network usage policy. Setting the action "Close Client and Server" blocks users from chatting on Yahoo. This rule should only be applied to a WAN interface.
