Where does 2K3 store temporary internet files and cookies for the local system account ?

I am trying to execute a Coldfusion cfexecute tag which runs a visual basic program that I wrote. The program grabs a webpage and downloads it. There is a cookie that shoud be associated with the download request. Coldfusion uses the local system account to execute the program. I thought if I could add the cookie to the local system account location where Win2K3 stores this, it would save me a bunch of coding compiling the cookies manually and acting on redirects. Any input for where I might be able to place the cookie to try this would be greatly appreciated. I have also considered the "runas" program to launch my program but I'd rather not have an admin account username/pass in a file. If you have any other ideas I have not considered, I am open to those as well. It has also been suggested to change the Coldfusion service from using the local system account to another user, but I am hesitant to do this as it could have many other reprecussions. Thank you again for your time.
