public class ConnectionImpl

extends Connection

Provides a concrete descendent of the abstract "Connection" class that can be used in any J2ME environments. It relies only on HTTP, which is the only protocol that is mandatory in the Generic Connection Framework. The class implements the client side of a TCP-through-HTTP tunnel (which sounds somewhat absurd at first sight, but makes sense in the J2ME scenario). The server part is implemented by the servlet contained in the de.trantor.mail.proxy package.
