SYMPTOMS
When you use a POST method over HTTPS to access a server
script that streams back a Portable Document Format (PDF) file, you may receive
the following warning message:
This page contains both
secure and non-secure items. Do you want to display the non-secure
items?
RESOLUTION
To resolve
this problem, obtain the latest service pack for Microsoft Internet Explorer
6.0. For additional information, click the following article number to view the

obtain the latest service pack for Internet Explorer 6
After you apply the fix, you must make sure that the
Web server that you download the PDF file from sends "Accept-Ranges: bytes" in
the HTTP Response Header. However,
this problem still occurs when the header is sent if the PDF file is less than 8 KB.
To
work around the problem in this case and send the header, pad the
PDF file so that its size is greater than or equal to 8 KB.
