PS, In the message below I meant to say InternetSetCookie() which is the real Win API.

>In my application I use AddPersistentCookie() to add a cookie to the users machine so that when they are then directed to a web form on my web site certain items will already be filled in. Most importantly is a Serial Number which many users will mis-type if left to fill in the web form on their own.

>The problem is that AddPersistentCookie() adds cookies that only IE will see and not FireFox. Does anyone know of a programmatic way of adding a FireFox cookie to a users machine similiar to AddPersistentCookie()?
