Session handling for mobile devices is a little bit tricky. Cookies sometimes are not supported by devices/gateways and transient session ID’s are to be considered as potential security issue. It is up to the programmer to decide which way to go by setting the according control flags in php.ini. The HAW_deck class offers a function called enable_session() which is helpful in case that trans_sid session handling applies: As XML does not allow unescaped ‘&’ characters, the arg-separator has to be modified. Otherwise a WAP browser’s WML decoder will crash, because WML is a XML-based language and therefore has to escape ampersand characters as &. An additional problem are the PHP-predefined url-rewriter tags. These are normally based on HTML. In WML there a tags defined, where url-rewriting has to be done too, e.g.
