SYMPTOMS
When you browse to a page through HTTPS, you may receive following Security Information warning message:

This page contains both secure and nonsecure items.

Do you want to display the nonsecure items?

This occurs when the page contains an IFRAME that does not specify a SRC attribute.



CAUSE
The warning message occurs because Microsoft Internet Explorer is unable to determine if the SRC attribute of the IFRAME is secure or unsecure.



RESOLUTION
To resolve this problem for a page that will be downloaded through SSL, set the SRC attribute of the IFRAME.

If the IFRAME is not expected to have a SRC attribute initially, point the IFRAME to a dummy HTML page.
