remove everything after question mark

Do you want to redirect the client with the updated path-only location or do you want to rewrite it before the request is sent to the pool? Do you want to do this with all requests that contain a query string?

With a redirect, the browser's address bar will show the update. With a rewrite it will not be modified. Here are two examples:

Rewrite:

  
  when HTTP_REQUEST {  
    
      Check if there is a query string in the URI  
     if {[string length [HTTP::query]]}{  
    
         Rewrite the URI to remove the query string  
        HTTP::uri [HTTP::path]  
     }  
  }  
  

Redirect:

   
  when HTTP_REQUEST {  
    
      Check if there is a query string in the URI  
     if {[string length [HTTP::query]]}{  
    
         Redirect the client to the same host and the path (URI without the query string)  
        HTTP::redirect http://[HTTP::host][HTTP::path]  
     }  
  }
