Re: expiring pages and reloading (ASP)

I developed the shopping cart system for www.icelebrate.com and we had the 
same problem.  As far as I know, there are two ways....

1) add a timestamp parameter to the end of the URL for every link in your 
website so IE will get a fresh copy of the page from the server.

2) use the no-pragma cache in the META tags.

I went with the 2nd option.  Let me know if there are any other solutions.
