This is not a Midgard (or even a PHP) problem -- it's just the way HTTP
works. Every request to a webserver is an event without external reations.
Keeping state is one of the more challenging things since HTTP was
designed to be stateless. Even logging in (a misnomer BTW) doesn't create
any kind of state. The entire logonm process is performed for every single
page request.
What you want is a session, and there are several ways to get that. One is
cookies, as you mentioned, another is requiring a login and store
username-related session info server-side, and a third one is to have
hidden values in a form and make each request a form action.
