Request::getPort()

Returns the port on which the request is made.

This method can read the client port from the "X-Forwarded-Port" header when trusted proxies were set via "setTrustedProxies()".

The "X-Forwarded-Port" header must contain the client port.

If your reverse proxy uses a different header name than "X-Forwarded-Port", configure it via "setTrustedHeaderName()" with the "client-port" key.
