Previous approach failed in case of routing table like:

    {
      'domain.com': 'localhost:9000',
      'a.domain.com': 'localhost:9001'
    }

without `hostnameOnly`. When routing request to `a.domain.com`,
`RegExp` matched first entry (`domain.com`) and returned it.

Instead, just perform a request.

This handles the case where a back-end web application such as Django or
Rails issues a redirect and automatically decorates the URL with the
protocol with which it was addressed.  If the back-ends are internal and
HTTP-only, then they'll issue a URL with 'http://' as the protocol.
This must be fixed before leaving the proxy.

This also handles the (unusual) case where a back-end speaks only
https://, but the user is deploying node-http-proxy to make that service
available to non-SSL capable browsers.  Works only with 301 and 302
codes.

error-prone in-line method.

_getKey() will look for options.target as well as
options.host:options.port, and so is useful for a segmented
proxy server where the destination proxies are not constructed before
first references.
