I am presently attempting to discover the way the internals from the HTTP server works.throu

I’m wondering when the HTTP Server keeps its connections through the message flow till it's been confirmed the response continues to be effectively delivered to the customer.

For example if we’re attempting to send a note from the to C using the HTTP Server a b - among.

A -> B -> C

Say a note is distributed from One place to another to C. C responds having a response message through B but B fails to get at A. Does the HTTP server tell server C that there is a mistake delivering the content to some or has got the B to C connection recently been closed with that stage?

I’ve trolled the internet but have discovered nothing to date.
