Because you are setting cookies using a normal cookie standard, you should be able to test all your cookie functionality in a normal desktop browser.

Try viewing your channel in a desktop browser such as Netscape or IE, but alter your preferences so that your browser prompts you before adding a new cookie. In Netscape or IE, remove all your old cookies set by your channel, and then try viewing your page again.

You can use a shareware program such as CookiePal to tell you the values of your cookies. Or, if you are using Netscape 6, you can use the View Stored Cookies button in the Cookies section of your preferences to view your current cookie status.

In addition, you can create a script to print out all HTTP headers that are being sent to your site and view that page through the AvantGo Client. That should display any cookie information that the AvantGo Client is sending to your site for your account.
