[Q][D2JC] How to pass an initial parameter in D2JC

Hi,

This D2JC requires users to authenticate with a user name and a  
password, but also a license code. The latter is usually just a  
unique company name. The idea is: a company buys a license and gets  
severe login accounts, each with a specific user name and password.  
The license code is unique within the system, but it is not secret,  
like e.g. the password. User account names are only unique in  
combination with a license.

Now I would like to be able to give users a company-specific URL that  
contains the license code, e.g. http://....MyApp.woa? 
license=mycompany, as a more convenient way starting the D2JC  
application, perhaps showing the company logo in the login window  
(I'm using Apple's example JCAuthentication framework).
The question is where in the session startup procedure do I get a  
chance to handle such URL parameters?

Any help much appreciated.
