Extended custom HTTP Headers

X-Bifrost-Target

This field directs the forwarded target to the websocket tunnel's peer side, it is like the proxy_pass director in Nginx. If this header field is set, the proxies item in conf.yaml will not be taken into consideration.

e.g.: X-Bifrost-Target: https://www.google.com
