I want to implement a Snort rule in McAfee NSM. But I get the Error "Validation failed: Invalid or unsupported PCRE token:pcre: /^(?:GET|POST) /(?:watch|search|find|results|open|search|close)/\?(?:text=|from=|aq=|ai=|ags=|oe=|btnG=|oprnd=|utm=|channel=|itwm=)/ ERROR: Unsupported PCRE syntax.
When I delete all "?:" from the PCRE the syntax is valid. What can I do to get this work?
