favicon troubles keeps resulting in http 302 redirect

Hi, webacceleration profile isn't used.

This is the irule which is causing the problem:

when HTTP_REQUEST
{
   set RequestedPath [string tolower [HTTP::path]]


   switch $RequestedPath
   {
      "/"
      {
         HTTP::redirect "https://x/north/"
      }
      "/north"
      {
         HTTP::redirect "https://x/north/"
      }
      "/south"
      {
         HTTP::redirect "https://x/south/"
      }
      "/north/"
      {
         HTTP::redirect "https://x/north/"
      }
      "/south/"
      {
         HTTP::redirect "https://x/south/"
      }

      default
      {
         if { !($RequestedPath starts_with "/n") }
         {
            HTTP::redirect "https://x/north/"

         }
      }
   }  
if { $RequestedPath contains "/north" }
   {   
if {[active_members Pool_x-north] > 0 }
      {
         pool Pool_x-north
      }
      else
      {
      if {[active_members Pool_www.y.nl] > 0 }
         {
            HTTP::redirect "http://www.y.nl/error/"
            TCP::close
         }

      }
   }
   elseif { $RequestedPath contains "/south" }
   { 
if {[active_members Pool_x-south] > 0 }
      {
         pool Pool_x-south
      }
      else
      {
         if {[active_members Pool_www.y.nl] > 0 }
         {
            HTTP::redirect "http://www.y.nl/error/"
            TCP::close
         }
      }
   }
}
