curl

When I look at this published Google Docs document, I see the latest version with Firefox and Chrome, but an older version with IE8. Also, screen-scraping it via PHP/Curl gives me an older version.

I've tried CTRL-Refresh in IE8 but I can't get it to show me the newest version. No matter what headers I try to change in PHP/Curl, I can't get it to show me the newest version.

What am I not understanding about browsers/headers/caching here? How can it be that different browsers show different contents of one page?
