How to set a destination HTTP path when dealing with WS frontend to HTTP backends?

[luistilingue]

Hi.

Reading docs, I don't see any way to set a HTTP path when using over_http to "convert" WebSockets from clients (downstream) to HTTP when connecting to backends (upstream).

Eg.

*,proto=ws,ssl=yes localhost:9001/path-a,ssl

Is valid such example?

This is possible with replace_beg:

*,proto=ws,ssl=yes,replace_beg=/path-a localhost:9001,ssl,over_http
