HTTP Keep-Alive Agent

forever-agent is a Node.js module that provides an HTTP Agent designed to maintain persistent socket connections between `http.request` calls, enabling HTTP keep-alive behavior. It was originally an internal component of the widely popular, but now deprecated, `request` HTTP client library. The current stable version, 0.6.1, was last published over 11 years ago in April 2015. With the official deprecation of its progenitor `request` library in 2020, forever-agent itself is considered unmaintained and has seen no significant updates for over a decade. Its key differentiator was offering direct control over connection pooling for keep-alive outside of the `request` library, at a time when native Node.js HTTP client features were less developed regarding persistent connections.
