Description

We should be able to customize the URLConnection used for read operations so we can configure things like userAgent. I don't necessarily want people to know that I'm using Java to probe their sites

JsonFactory._optimizedStreamFromURL() takes a URL and returns an InputStream using URL.openStream(). URL.openStream() is shorthand for url.openConnection().getInputStream().

I propose that we register some sort of factory with ObjectMapper that takes in a URL and returns an InputStream, then use this factory in optimizedStreamFromURL().

Interesting. Yes, I can see why this would be useful.

Ah. So, with current version, you can sub-class JsonFactory and override "_optimizedStreamFromURL" to do this. But it would be nicer to allow some other means of overriding this.

My only real concern is that of not wanting to add much to core jar; so it would be nice to find a way to avoid adding new classes. Hmmh. There is already "java.net.URLStreamHandler", with openConnection() method – I guess that would be the way to do this, allow setting instance.

I think I will not add support for this, since users can override deserializer used for handling URLs.
This seems better way to customize handling based on specific requirements.
