> The browser connects to the server, opening a connection, receives the necessary data, then the connection is closed. Or does it not close and is open for a while?
http/1.1 and http/2.0, if my memory serves me, try to keep connections open. the time is now such that sites like to drive data back and forth between the web server and the browser.
> If so, what kind?
weird question. well, let's say, any for which the close procedure was not initiated at the end of the transfer of the web page.
> 247 is an amount of connections on which data is transferred right now?
no, it's the total number of established connections.
> Do I understand correctly that if I have 1 css file and three pictures on the page, in the case of using http2, all this will be transmitted over one connection, and otherwise, 4 connections will be opened?
in the case of http/1.1, this can also be a single connection.
