Secure and nonsecure warning in IE using https (SSL or TLS)
We've just been running our site using SSL (https).
Mostly it's fine but occasionally when changing the screen we get the
dialog saying "This page contains both secure and nonsecure items. Do you
want to display the nonsecure items?"
This last happened with iframe - see
In this case I have used Fiddler and intercepted the https stream, and
confirmed that at the point of clicking on the item in our application
where this warning appeared there was no request for an http item.
