Timeouts for instance.

For instance, is it possible to get "preemptive authentication" with HUC? Is it possible to connect with SSL to a server using a self-signed certificate with HUC? I'm familiar with doing preemptive auth with HttpClient, but I only briefly read about the self-signed cert issue a long time ago.
Both scenarios should be possible with HUC. The problem is that HUC API
is just plain ugly and cumbersome, and this can affect your application
code. For example, one can use protocol interceptors with HttpClient in
order to introduce a cross cutting aspect for all outgoing requests and
incoming responses, which is simply not possible with HUC. So, the
differentiating factor is the quality of API, not the feature list. Just
pick the one you like better.

Actually, timeouts is one area in HUC that was fixed in JDK 1.5. There are now setters for "readTimeout" and "connectionTimeout".
Your point about the convenience of the API is well-taken.
