What does the browser do when the server does not respond to the connection for a long time?

Question

Browsers

When there is no response over HTTP for a long time - what happens in this case in the WebKit browser and in NodeJS?
Will retries be sent? Through what time interval?
Where can I learn more about this technical details?

Answer 1

As far as I know, HTTP itself does not regulate this in any way, so it remains for the client to inspect.
WebKit most likely waits until a timeout, then terminates the connection.
NodeJS - there may be different clients / libraries and behave differently too, but with a high probability they do the same by default
