I'm using the following code to load a tab with a dynamically generated (iText) PDF. The tab itself is dynamically created, and loads my new PDF just fine. However, after the PDF is loaded in the tab, I DON't WANT the tab to send a new request off to the server to regenerate a new PDF when I switch between tabs. IE 6&7 display the tabs archived content (desired behavior). However, FireFox sends off a new request and retreives a new PDF when switching between tabs. I'd like to just display the original PDF.
