When creating PDFs dynamically, you have to be careful with your cache-control and expiration headers when your dealing with IE clients.


Basically, don't use them. Otherwise, your server will have to generate the PDF twice, and your user will have to download the PDF twice. IE doesn't seem to realize that it already has the file. It's not a big deal for users with a fast connection, but it can be painful for dial-up users.
