Answer 1

Some time ago I've got a problem with IE6 opening pdf files, and crashing when AdobeReader 6.0 was installed and tried to open file in browser window. Than I found somewhere this header:

header('Content-Type: application/force-download');

And it solved the problem, every pdf file was downloaded and opened in Adobe instead of IE.
