I'm working on a system integration with TIBCO EMS as middleware. In TIBCO they have configured servers in FT mode and provided 2 different URLs. They are expecting me to handle this in case of primary server crashes I should redirect the request to backup system.

Is there any need to manage these 2 urls client side for fault tolerance or TIBCO EMS itself is smart enough to handle this by exposing only 1 URL to the client.

Kindly advise on this.
