Maybe something like this? 


when HTTP_REQUEST {

    Check for /install/ or /scripts/ in the path
   switch -glob [HTTP::path] {
      "*/install/*" {

          Parse the URI "directory" after install. Look for /install/, skip 9 characters and match up to the next /.
 set session_id [findstr [HTTP::path] /install/ 9 /]
      }

          Parse the URI "directory" after scripts. Look for /scripts/, skip 9 characters and match up to the next /.
 set session_id [findstr [HTTP::path] /scripts/ 9 /]
      }
      default {
 set session_id ""
      }
   }
   if {$session_id ne ""}{

       Persist on the parsed session ID for X seconds
      persist uie $session_id 1800
   }
}
