Question

Answer 1

URLConnection is an easy but somewhat "dumb" class. I can suggest you to do it the Java way: instantiate a new URLConnection. ;) Java is not really a language that encorages reusage of objects.

You can try resetting the input stream, see the docs for more info, but I don't think it will do another GET. Who knows how the concrete implementation behind InputStream and OutputStream of URLConnections is done.

EDIT: I don't guarantee anything, but you could also try to disconnect() and then connect() again. Never tried it, see if it works.

Answer 2

By default there is no way. If you really want this feature, you have write some code for that. Write a URLHandler which gives a socket wrapper, that does buffering. Implement reset methods() as you like.
