I believe this related to a known issue with Internet Explorer where it
ignores the first response content and sends a second request...
although I only know that to happen with certainty when hitting a
doPost() as opposed to a doGet(). This problem has been nagging us (and
our customers) for several years. There are a couple workarounds we've
been able to make work, but the most reliable is to write the PDF to the
filesystem and return an HTML redirect as the response.
