Fixes #178

So this is better, but I would note that the sentence ("If the recipient is configured to use another HTTP server ...") is actually biased towards an HTTP Gateway, i.e. an HTTP server side HTTP Intermediary rather than also cover client side HTTP Proxy. As this type of proxies the client are configured to use them, but they will process the HTTP request and determine how to forward it based on the host information in the request.

@gloinul I agree with you that the common instance is that of a gateway, but the term intermediary is also correct. Are you suggesting a change to this PR or are you OK with it?

I think it is the word "configure" that I have issue with. As the recipient doesn't need to be configured to use another HTTP server, just to be a HTTP intermediary. I think what would be clearer are:

"If the recipient is configured to be an HTTP intermediary, it will forward the request to a HTTP server or another HTTP intermediary."

This sentence is just to provide a context for when the following note applies.

[DavidSchinazi]

If the recipient is configured to be an HTTP intermediary, it will forward the request to a HTTP server or another HTTP intermediary.

That's not quite right, an HTTP intermediary is an HTTP server - the server is simply defined as the one who receives the request and sends the response. In other words, an intermediary is both an HTTP client and an HTTP server, but in this case it's the server half that's relevant. So it doesn't make sense to say "to a HTTP server or another HTTP intermediary".

We could therefore imagine saying the following:

If the recipient is configured to be an HTTP intermediary, it will forward the request to another HTTP server.

But at that point I prefer the text in this PR, I find it more clear.

@gloinul do you have any more thoughts? This is the last remaining discussion point, it would be nice for us to resolve it.
