There's already an agent option, but it doesn't look like it's fully implemented. What do you think about using agent instead of httpAgent?

you're right; agent + httpAgent certainly makes things confusing; possibly docs update to clarify better?

code wise it looks like this

http.request(options);
  ^               ^  
  |               |
httpAgent         |
                agent

e.g. lib/http-proxy/passes/web-incoming.js:125

my use case was to replace tls with custom module for https requests

[codebling]

Oh, I see - this is where we could use something like e.g. axios or got instead of actually using http module's .request() with something that http.Agent, right? But httpAgent here would still need to implement the http.ClientRequest interface? So...not axios or got? Wouldn't the TLS changes have mostly been specific to the agent anyhow?

There's probably room for refactoring to provide a single configuration that allows both (e.g. hooks for creating connection and getting the stream), but it's probably moot anyhow, since this your PR is going on 4 years old, there have been no commits in almost 2 years. Perhaps a strong ping in the "New Maintainers" issue would receive a response, as indexzero does seem to still be relatively active on GitHub.

thanks, your mentions probably already have alerted maintainers. let's see what's suggested.
