Sorry if you think I'm nitpicking, but the interface you've designed
isn't actually RESTful:


In particular, you're making a POST request to make a read-only request.
A GET would be more appropriate here, if nothing else but to make it
easier for the web server (or an inline proxy) to cache requests for you.

You also send the accept header with "*/*" though you actually expect
and can only handle json.

I think a better interface would be something like:

for an ANY query:


for specific queries:


And pass in the other request info as http headers, maybe:


Perhaps pass in the remote IP with the X-Forwarded-For header, which
seems kinda cute, though probably a bit wrong really.

Doesn't have to be restful of course. You could just leave it as it is
and rename the backend to just something like "http".

Also, you should handle multiple records in the response (I don't think
you do currently). This is especially important with ANY queries.

Hope that's useful.
