Proxying or rewriting http traffic

Hi Chris -

 

 

I'm not sure you need an iRule at all...

 

 

LTM is a full basic IP proxy. By default, if you configure a virtual server with a pool of real servers as its only resource, requests passing through the virtual server will have the destination address/port translated to the selected real server's address/port.

 

 

For HTTPS traffic, you can apply a clientssl profile to the virtual server, which enables backend communication with the real servers via HTTP, offloading the crypto processing overhead to LTM.

 

 

Some applications cause the client to imbed the destination address elsewhere in the data stream, which proscribes proxying connections in this manner, but I've not run into WebSphere displaying that particular idiosyncracy.

 

 

A clearer description of how you need to modify or interact with the existing data stream would help determine whether an iRule is the solution here...
