The URL Handlers Service already abstracts URL schemes and content types.

It would be nice if the URL Handlers Service would also provide a Default Authenticator
http://docs.oracle.com/javase/1.4.2/docs/api/java/net/Authenticator.html#setDefault%28java.net.Authenticator%29
where bundles can plug in Authenticator services.

In the simple case the URL Handlers Service can ask all registered Authenticator services if an provide any useful authentication.

It might be wise to specify a service property where Authenticator services can specify which URLs they can provide authentication information for example

url.authenticator.url = http://secretsite.test/secretdata/*

would specify that the registered Authenticator services can provide authentication for urls like http://secretsite.test/secretdata/picture.png or http://secretsite.test/secretdata/sounds/voice.wav but not for http://secretsite.test/otherdata.html

This would make the URL Handlers Service even more useful than it currently is :)
