URLStreamHandler is the common
jaroslav@327: * superclass for all stream protocol handlers. A stream protocol
jaroslav@327: * handler knows how to make a connection for a particular protocol
jaroslav@327: * type, such as http, ftp, or
jaroslav@327: * gopher.
jaroslav@327: *
jaroslav@327: * In most cases, an instance of a URLStreamHandler
jaroslav@327: * subclass is not created directly by an application. Rather, the
jaroslav@327: * first time a protocol name is encountered when constructing a
jaroslav@327: * URL, the appropriate stream protocol handler is
jaroslav@327: * automatically loaded.
