If I understand the rules docs correctly (and there's no guarantee that
I do), the depth parameter is measured from the beginning of the
payload, not from the beginning of a previous content search

content:"javascript\://"; nocase; content:"\\n"; depth:255;

Can you use regexp wild cards like this?


Or better yet, like this?


And should we take this discussion to the snort-sigs list?  (I'm ccing
it just in case we should.)
