Technology is a wonderful thing.

Web browsers are technology.

Web browsers are not always wonderful things.

IE + HTTPS + SWF + ‘Pragma: no-cache‘ + ‘codebase=http‘ == Bork bork bork.  No graphs load.
Talk about seriously brain-dead, but at least it wasn’t as silly as the Eolas patent.

In the end, due to the SWF library we use to generate graphs, I had to use ob_start(); $chart->export(); header(‘Pragma: IE-Die-Die-Die’); ob_end_flush();

Blech.
