HAProxy URL based forward

[daker]

I want URL based redirection for my pfSense.
For example,

http://my.wan.ip/goto/abc  –> http://172.16.1.111
http://my.wan.ip/goto/xyz  --> http://172.16.1.112

172.16.x.x is internal address.

Is this kind of configuration possible?
If so, please guide me how to enable this with ACL and Actions in HAProxy Frontend configuration.

I found the ways using the belows.
I need to change backend not frontend.  :)
