Webdynpro and URL parameter passing

Hi folks,

With the ITS concept, one could pass on a couple of parameters (like the good old 'okcode') when calling an ITS application in order to bypass the first screen ... We are using it to bypass a customer logon screen for those customers that are already logged on via the portal ....

How does this fit with webdynpro applications? Passing parameters is ofcourse standard HTTP behaviour but how is it handled by a webdynpro application? Are the parameters by default available in the context controller? Can one bypass a complete view (so like the okcode for ITS) ?

Thx,

Steven
