alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"ET CHAT Facebook Chat (send message)"; flow:established,to_server; content:"POST"; http_method; content:"/ajax/chat/send.php"; http_uri; content:"facebook.com"; http_header; reference:url,doc.emergingthreats.net/2010784; classtype:policy-violation; sid:2010784; rev:3;)

This rule is the one that was downloaded from snort.org....I don't have any custom rule sets.

I'm able to go to facebook chat and chat up a storm with someone I know and I don't even get an alert on it.

What does your rule look like. Also, isn't that ssl traffic? Are you looking for connections to a certain domain?

Anyway, lets see the rule and in sure we can get this going.
