favicon troubles keeps resulting in http 302 redirect

Ah, I see the issue, corrected version;

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

 Redirect only if the HTTP path exactly matches one of the following; 
 switch $RequestedPath {
  "/" - 
  "/north" - 
  "/north/" {
   HTTP::redirect "https://x/north/applicationurl"
   Stop processing the iRule here
   return
  }
  "/south" - 
  "/south/" {
   HTTP::redirect "https://x/south/"
   Stop processing the iRule here
   return
  }
 }


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

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

 else {
   Can't serve fancy error page or HTTP path doesn't match
   Let's reject so clients don't have to wait for a timeout
   reject
 }
}
