HAproxy rewrite in Backend - url to internalip/path

[Airwave]

Hi all,

I tried now several backend http rewrites, but I didn't foud the final solution so far.

In pfsense with haproxy, I want to

call an url www.xyz.com in the browser and the application is loaded from a local server with a path e.g. on
http://localserver:81/mypath/...

I don't want that the user sees the mypath, as he also not sees, that se application runs on port 81 and not 80.

Think that is been done in the ACL section in the backend, but I don't get the right configuration.

Could you help me, please?

Thanks in advance.

Cheers
