It's not possible to do that; logic of that nature is part of why we have the PCRE engine. A lot of people seem to think PCRE should never be used, and generally cite performance concerns. The reality of it is, if used wisely, PCRE is a very useful tool, and should be taken advantage of wherever appropriate. Yes, there can be performance issues - but it can also be very fast, too.

Hi everyone! Any one, please tell me how to write a Snort rule with OR condition without PCRE? For example: write a snort rule that matches web POST method and content contains "--" or "#".
