Access Control Based On IP for specific URL

Small tweak to the iRule to handle case properly:

   
   when HTTP_REQUEST {     
     if { ( [matchclass [string tolower [HTTP::uri]] starts_with $::securePaths] ) and   
          ! ( [matchclass [IP::client_addr] equals $::trustedAddresses] ) }   
     {   
       log local0. "Untrusted IP ([IP::client_addr]) attempting to access secure path ([HTTP::uri])"   
       discard   
     } else {   
       log local0. "Allowing connection from [IP::client_addr] to [HTTP::uri]"   
       forward   
     }   
   }   
   

I have it converting the path to lowercase. This handles people trying to go to:

http://yourdomain.com/TeStInG

or other variants to try and get around your filtering. As long as you always use lowercase when defining entries in the datagroup you'll be good.
