iRule not always processing

I think the following a more simpler iRule:

 

 

   
   when HTTP_REQUEST {   
      if { [HTTP::header "Referer"] contains "gadget" } {   
           discard   
      }   
   }   
   

 

This simply means that if you have a referer that contains gadget anywhere in the header field it will discard. For example it was discard "gadget, disgadget, mothergadget, papagadget, gogogadgetchopper, etc" However, I am not sure if it's case sensitive. If it is then it the code could be written as the following:

 

   
   when HTTP_REQUEST {   
      if { [string tolower [HTTP::header "Referer"]] contains "gadget" } {   
           discard   
      }   
   }   
   

 

 

Click here if you want to look at HTTP::header function more closely.

 

 

Hope this helps
