How to redirect incoming URL IP to a different one depending on source

Help!
1

I have 3 networks (for test). I need users to be redirected to a different URL IP based on what network they are coming from. Example 10.32.0.0. I need to redirect to 10.32.1.1. 10.33.0.0 I need to redirect to 10.33.1.1, and so on. How do I do this?

I am new to HAProxy so sorry for the novice question
Thanks
