How to send H2 request to a server with a different :authority pseudo header?

[ibigbug]

The current behavior is, when a request is sent to, for example, "example.com", the H2 request pseudo header :authority is set to that value, derived from the Uri.

while in HTTP/1.1 I can easily send a request to "example.com" with a Host header to a different value.

but the H2 API doesn't allow me to set the :ahtority header directly, and it can only be derived from the Uri, changing the authority of which, will cause the request to ben sent to a wrong place.

How do I do that in hyper?

i'm doing this via implementing a custom connector with a fixed remote server, but not sure if it's the ideal way of doing this
