How to add SelectedMember to URI

I'm already running a HTTP_Request iRule for every request which validates and enforces a specific URL pattern.

 

 

I could add a line to that which stores the selected node's IP address into a variable.

 

 

That variable would then be available to the HTTP_Response? Such that the variable's value would be accurate to the matching HTTP_Request? I just want to make sure that the client's selected node is valid and that I can see the value in the URL.

 

 

I'm not sharp on the syntax for modifying the URI query and such... I could not find a reference to edit the URI Query... just to read it. I'm also not sure how to set a variable that would be usable by the HTTP_Response if set by the HTTP_Request.

 

 

Thanks for your help.
