URLStreamHandler Help

I'm trying to create a custom URLStreamHandlerFactory, but also I need to change this factory at times...specifically
in individual threads.

The API reference for JDK 1.1 says the URL.SetURLStreamHandlerFactory function can only
be called once in an application.  Does this apply
to individual threads?  Or does it really mean once
in an application?  Are there any workarounds?

I think the decision to make the factory a write-once variable was based on the desire to make the interface as lightweight as possible.  Changing the factory on the fly would require additional synchronization and hence more processing time.

Perhaps you want to define a class (implementing URLStreamHandlerFactory) that allows a thread to register itself (with its own map scheme-to-StreamHandler).  Then when createURLStreamHandler is called on your interface, you can find what driver to use based on the thread that you're executing on.

I suppose I could elaborate if this is going in the right direction.

Hmm... There is a problem...

Apparently URLStreamHandlerFactory is only called once
for each specific protocol...

My solution, I think, will be to create a URLStreamHandler,
(as well as a URLStreamHandlerFactory) which _is_ called by
different threads, and will be able to return the URLConenction
as necessary.. this takes out some of the functionality
I had hoped for..but should still be acceptable.
