There is an answer but it depends on how you use WebLink. If you use the F1 WebLink login page then we right a session cookie with a 20 minute timeout. This allows for all of the WebLInk modules to simulate single sign-on. It was built for home use, not necessarily for a public use computer. Last year we added a new option to all of the WebLink modules, except Event Reg. Simply add "flo=true" (stands for force log out) to the end of the URL querystring. This will clear the cookie when the browser closes. Why did we not add it to Event Reg? Because it is a multi-page wizard.
The alternative is to write your own login page using Data Exchange (our XML API). You can see an example at www.Dynamic-Church.com. This way you can write the cookie and control it's timeout and behavior.
I have some additional details and examples in a presentation I gave at last year's user conference. Please give me a call at 469-442-0100 to discuss further and I'll send you the presentation.
