Response modification proxy

We want to define a proxy in the BigIP that transform a response using an external server.

 

 

Here is the use case

 

 

1) a client makes a request to the BigIP.

 

2) The BigIP receive the request and make the resquet to the Origin server.

 

3) The Origin server return the response to the BigIP

 

4) The BigIP receive the response

 

5) The BigIP then use the Response and few headers from the original request and call an external server

 

6) The external server return a response to the BigIP

 

7) The BigIP returns the response to the client

 

 

Can you provide code sample that could help us start.
