Hi, James-

This rule has been reviewed and committed to the community ruleset. In 
the committed version I used the within content modifier to enforce 
order and length.  Additionally, I changed the formatting from:



content:"idcontact.php|3F|"; http_uri;

Thanks for your contribution!  Best,

Matt Mickel
