I've watched the HTTP interaction in Fiddler Tool in IE and Opera and I
don't ever see the final redirect header being sent (can you do that after
sending raw data?). Have you tried just dropping step 5 to see if there's
any difference?

If you really want to trigger a reload send them to URL.'?'.time() to
guarantee the page isn't cached.

Better idea: generate the PDFs offline and store them on the filesystem.
you can still serve them the same way if you need to using something like
PHP's readfile().
