Is there a way to limit number or requests on a KeepAlive connection on net/http server?

[zohaib...@doordash.com]

Hey folks,

 I've been digging around for a while but could not find anything; is there something with builtin HTTP server that I can do to limit the maximum number of requests allowed with KeepAlive connection? I found fast http provides an option MaxRequestsPerConn to do so, https://github.com/valyala/fasthttp/blob/59b28fe0e54664073ac4e422511ca8af718b26b0/server.go#L233-L239 is there something out of the box too? If not I really want to stick to stock net/http package; is there a quick cheap way to do that?

Use Server.ConnState to count idle connections, and close them as you wish.

I don't think you can limit the number of requests by the MaxRequestsPerConn of fasthttp, because the Conn in this func is new struct created by fasthttp which stores in pool. Real client connections will be send to channels which be processed by these Conns.

For @ Tamás , Server.ConnState applies to net connections, not request on the keep-live connection.
