Discussion: Are connections re-used + HTTP 1/2 support

[michaelfeil]

Hey all,

just came across this project from this discussion: https://github.com/seanmonstar/reqwest/issues/2677 .

A couple of quick questions

• is hyper re-useing the connection for http1.
• are http2 connections multiplexed?
• are http1 handshakes reused? https://github.com/seanmonstar/reqwest/blob/5b705ccc6bed87f8bf1b6a980049c6764ffdf493/src/async_impl/client.rs#L952

Good morning. Sorry for the delay in response. Hope this helps.

is hyper re-useing the connection for http1.

The default hyper client maintains a connection pool, regardless of the connector used, so yes, it should be re-using the connection.

are http2 connections multiplexed?

By default, our crate enables hyper-rustls/http2 support, which does multiplexing of requests.

are http1 handshakes reused?

Yes, I believe this is the case.

@keelerm84 It does not work out of the box, you need to pass in a hyper client.
