Upgrade http-proxy dependency >= 1.18.1 ?

[mr-m0u5e]

Hi @Rob--W,

Are there any plans to upgrade http-proxy dependency? Unfortunately the current http-proxy version 1.11.1 does not pass npm audit, and that in turn crashes our CI pipe. My understanding is that there are some undocumented http-proxy features that prevent the upgrade?

Thank you for your work, really enjoy this package.

There was an attempt in bug #247, but it was closed because of the efforts and unknown benefits. This issue sounds like a good driver to resume the work.
