in reply to IE 6 PDF creation on secure pages

1. You could try 'curl' from the command line with -D to dump the headers:

curl -D - url?querystring

2. I had a problem with IE refusing to display a PDF that had a 'Cache-control: no-store' header.

3. You might also want to disable 'byte serving' with the 'Accept-Ranges:' header.

4. Good luck
