rpc

My WebApp needs to authenticate user before allowing any sort of access. The scenario I'm trying to implement is a login page with username and password fields. Once user hits "send" button, a sign like "Verifing..." should be shown up while an RPC call verifies credentials. In case of success, load the main app screen.

What is the best way to implement that?
