Dealing W/ Cookie-less Sessions
 By Raymond Camden
Axel asked a question about Vista Gadgets that I thought I would discuss here.
Sessions with MS Vista. I'm building a VISTA gadget calling an external CFM page using flash forms. It looks really cool, in particular in a flyout window.
Now when I need to log into the app, I realized that the VISTA Gadget space seem not to have any session handler. Any idea?
The first thing you need to do is uninstall Vista. (No, I jest.) So with knowing nothing about Vista Gadgets (frankly widgets and gadgets bore me) I'd have to assume that they are acting like a cookie-less browser.
ColdFusion sessions require cookies in order to track your browser and associate it with a session... normally.
If your browser doesn't support cookies, you have two ways you can handle it.
All sessions come with a few default variables.
One of them is URLToken. This is a string of the form cfid=XXX&cftoken=XXX (or cfid=xxx&cftoken=xxx&jsessionid=xxx). As you can see, it is in a format appropriate for query strings.

This allows you to append it to the end of a link:
The important thing to note though is that all links have to use one of these methods.
That means both "simple" links like I used above as well as form tags.
It would also include AJAX links if the back end needs session information in order to return the correct data.
