irule for request and response

All,

 

Looking to irule a request and response header edit for https://example.com/x/y

 

So, that when user inputs https://example.com/x/y , request is sent to server as https://example.com/y

 

Anything input into y as a string is request to server.

 

I have created this:

 

when HTTP_REQUEST {

 if { [HTTP::path] equals "/x/y" }{ 

  HTTP::redirect "/y/"

 }

}

 

This returns above irule https://example.com/y . but, the ask is to add x back to the response and return https://example.com/x/y to the user.

 

The parts I am working on now are the response edit and how to use the string input by the user - y - to reflect anything. Similarly, to x when responding back.

    So, I got some direction...

     

    Here are the three possible paths : 

     

    /x

    /y

    /z 

     

    Each could have another resource behind the initial path i.e. /x/ping or /x/file or z/path or z/box.

     

    The other resource /ping or /file or /path or /box is what I don't know will be called but needs to be requested to the server and /x, /y, or /z needs to be edited out and only the second resource needs to be sent to server.  

     

    So user puts in /x/ping and /ping gets request to server.  

     

    Similarly, when the response is sent back the first resource needs to be added back. As in if we called /x/ping, x would be add back from the server that only was called /ping.

     

    So.. all that written, let me see how to apply the below with x.  

     

    when HTTP_REQUEST {

      if { [HTTP::uri] starts_with "/x/1" } {

        #Comment:The string map is used to replace the uri value from /uri/1 to /uri/2.   

        HTTP::uri [string map {"/x/1/" "/x/2"} [HTTP::uri]]

        pool pool_x

      }

     

    when HTTP_RESPONSE {

      if { [HTTP::uri] starts_with "/x/2" } {

        HTTP::uri [string map {"/x/2/" "/x/1"} [HTTP::uri]]

      }

     

     

    So, with the three first resources - x, y, z - and this all being one virtual server, would I just create three irules and apply them all to the one virtual server?
