HaProxy Forward

[Soloam]

Hello all, is it possible to forward a request in HaProxy similar to ModRewrite on apache, for example, I what to:

http://mydomin.local => http://otherdomain.local/folder1/folder2

For example.

I'm able to make the forward with code 301, but I would like to make some kind of encapsulation, to the browser we are on http://mydomin.local but in the background the requests are being send to http://otherdomain.local/folder1/folder2

Is this possible? (before any one asks, I can't do that on the server side because I don't have full access to it, so I would like to use the reverse proxy to this)

Thank You
