If you have 80 URI's to match against, it would probably be easiest to administer if you defined them in a class (data group in the GUI) and used the matchclass function to perform the test.

Here's an example class:


class uris {
   "/uri1/"
   "/uri2"
}

And a rule that references the class:


when HTTP_REQUEST {
   if { [string tolower [matchclass [HTTP::uri]] contains $::uris] }{
      node 10.102.180.69 80
   }
}
