Is Haproxy url based routing ?

Issue

• If there is a url called "www.testurl.com?test=orange" then I would like the ha proxy to route the request to the service "orange". However, when the url ""www.testurl.com?test=purple" comes through the HaProxy, I would like it to automatically route request to the service "purple".
• Is it possible to access application like: www.example.com?test=orange or www.example.com?test=purple instead of www.example.com/orange and www.example.com/purple
