But I realized afterwards that although technically everything was there to write good HTTP client code, it was way too difficult (it required to much code on the user's behalf).

It is somewhat similar to Gofer like classes. It is also somewhat comparable to ZnHttpClient but it contains even more functionality.

In the current Zn version all ZnClient class functionality as well as all ZnHTTPSocketFacade (and thus HTTPSocket and thus the rest of the image) has already been reimplemented using ZnNeoClient. These are good examples to look at.

So… is that URL already percent encoded? If it isn't how do I specify
what encoding should be used? ;-)
