If it turns out that mgmt DOES want just web traffic, the use of the http_header
will tell the sensors to stop alerting on the content on pages then correct? I
have been getting false positives where a user visits a page with a link or
mention of “crappydomain.com” on it and that visit sets off the alert…

this is exactly the false positive i was speaking of... forum pages with 
discussions about crappydomain.com was one i was thinking... these mailing list 
posts are another very prominent example ;)

did you see my offering where we use content like you are and then include an 
anchor on the http host header without using the http_header option?
