The test coverage for NTLM http authentication is currently limited due to the dependency
on availability of test servers. A better approach for testing is illustrated in
the new test case test/sun/net/www/protocol/http/NTLMTest.java.

Basically, it should be possible to use hard-coded NTLM exchanges like this
to simulate an MS http or (proxy) server.

What's needed is a set of tests similar to the one above, but which cover as
much of the NTLM functionality as is practical (ie. both server and proxy authentication)
