I am using CSS3Pie via the PIE.php script and am facing some very weird trouble with IE 9.
When using the file as-is, certain pages cause IE to load PIE.php endlessly on first load. If I reload the page, everything is OK. Also, if I load another page that uses PIE.php, and then navigate to the specific problematic page, everything is OK as well.
If I modify PIE.php to send no-cache headers, IE 9 will always load PIE.php endlessly.
Fiddler screenshot attached.
All calls to PIE.php come back with:
