How can you use Servlet Session Tracking with WAP?

[More question: I am trying to implement a simple access - login - re-direct mechanism using WAP / WML, however the WAP browser does not seem to support normal session tracking. Do I have to explicitly (and dynamically) place the sessionid in the login form?]

Many WAP browsers and/or proxies do not understand cookies and/or redirects. This means you will have to use URL rewriting for your session management. Feel free to complain to the WAP product vendors -- these are basic HTTP features that really should be implemented.
