HTTPS + Flash + IE + Dynamic XML = Bug

How was web development done before Google? A site we're releasing just got hit with this IE bug that occurs when you're running Flash through https. The full description of the problem can be found here.

I was able to find a solution in about an hour. Before internet search it probably would have taken days to get to the bottom of the problem, and might even have required communications with Microsoft.

Adding these two lines to your page rendering PHP fixes the problem the problem:

header(“Cache-Control: cache, must-revalidate”);
header(“Pragma: public”);
