Data Group and URI

I suppose you can do something similar to

NOTE: This is untested

 
 when HTTP_REQUEST { 
   if { not [matchclass $::affiliateid eq [findstr [HTTP::query] "kbid="]]] } 
         reject 
      } 
 

You have to define the data group and fill it with your affiliate white list

The reject will simply cause the connection to be rejected, returning a reset as appropriate http

Hope this helps
