iRule / uri parameter manipulation

Is the update actually being made in the request to the server? Maybe it's a problem with caching of the HTTP:: commands. I thought using HTTP::query would have shown the update. Can you try logging in a second HTTP_REQUEST event?

 
   when HTTP_REQUEST {   
  
       Check if path ends with /searchresults.aspx 
      if {[string tolower [HTTP::path]] ends_with "/searchresults.aspx"}{   
  
          Rewrite URI for u=https:// to u=http:// 
         HTTP::uri [string map -nocase "u=https:// u=http://" [HTTP::uri]]  
  
         log local0. "[IP::client_addr]:[TCP::client_port]: Updated query string to [HTTP::query]" 
      }   
   } 
   when HTTP_REQUEST priority 501 { 
         log local0. "[IP::client_addr]:[TCP::client_port]: 501 Updated query string to [HTTP::query]" 
   }
