NodeJS How to permanently terminate connection with http client?

Question

JavaScript

Good evening.
How to terminate the connection with the client once and for all? So that the next time he connects, he has a new socket and a new connection in general.
Tried res.end(), req.resume(), req.pause() as soon as I didn't.
The problem is that an object is attached to each req during the execution of the POST request, and, with each connection, it must be re-initialized, that is, re-initialized. At the moment, if you make several POST requests from one tab, then this object will not be new, but remains old. How to be?

Answer 1

Send it a "Connection: close" header
