[Snort-sigs] Question about pcre syntax

Subject: [Snort-sigs] Question about pcre syntax
Date: Sat, 16 Feb 2008 14:10:34 -0600
Is this correct syntax for pcre?  Or will it not work at all?

prce:"/foo|bar|some|such|thing/";

The intent is to provide a bunch of ors that would match after a previous 
positive content match.

Would it be more efficient (less resource intensive) to write a separate 
rule for each match, even though the entire rule would be the same except 
for the second content match?
