You should be able to check what the original location header value was in the /var/log/ltm log file. The above rule wouldn't have modified the protocol. If you want to change it from http:// to https://, you can modify the rule: 

 
  when HTTP_RESPONSE {    
        
        Check if a response is a redirect    
       if {[HTTP::is_redirect]}{    
        
          log local0. "Original Location: [HTTP::header value Location]"    
        
           Assume the server will use it's own TCP port in redirects and remove it.  Also replace http:// with https://. 
          HTTP::header replace Location [string map -nocase [list http:// https:// ":[LB::server port]" ""] [HTTP::header value Location]]    
          log local0. "Updated location (string map): [string map -nocase [list http:// https:// ":[LB::server port]" ""] [HTTP::header value Location]]"      
      }  
   }
