Neat, thanks, I missed that in the docs. I should be able to tune it
down even further than this by throwing in more content values, but
I'll start here for testing (slightly obfuscated):

pass http proxyip any -> $EXTERNAL_NET 80 (msg:"Pass ocsp Verisgn
traffic"; content:"ocsp.verisign.com"; http_host; sid:#;)
