Enhancement Description
Many of the HttpURI methods are not documented. For example, it's not clear what the difference is between getParam() and getQuery(). getParam() sounds like it's related to matrix parameters, but maybe it is not.

I know that the class-level Javadoc touches upon some of this, but I'm asking for method-level Javadoc to be added.
