Haproxy redirect to path

Hi , I use haproxy on pfsense and in production 5 certificates managed by haproxy that are automatically sorted on lan servers .

The first certificate is that of the pfsense e.g. mypfsense.fqdn . Through this certificate I would like to add a path that points to an http server in lan. E.g. https://mypfsense.fqdn/servernalapp.local.lan

How can I do it?
