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 So something like this wouldn't work, right? content:"javascript\://"; nocase; content:"\\n"; depth:255; Can you use regexp wild cards like this? content:"javascript\://*\"; Or better yet, like this? content:"javascript\://*{255}\n"; And should we take this discussion to the snort-sigs list? (I'm ccing it just in case we should.)
