We're working on an employee intranet site. It will be available over the Internet, so we're forcing https for all pages of the site.
We're now seeing that in IE9, on pages that have a Bing or Google maps instance, we get the prompted warning "Only secure content is displayed." The universal recommended solution I found for this is to set "Display mixed content" to Enabled in the security tab of Internet Options. This solution would be acceptable for our implementation, since our internal sites are in the trusted zone, and we could push out the custom security setting to all of our workstations. However, even after making this change the browser still prompts. I also tried closing and reopening the browser, clearing cache, and I verified that our site is in the Trusted Sites (where I changed the security level), and that Protected Mode is off for this zone.
Anybody have any other ideas that might work? Is this somehow caused by the way the instances are accessing the map data?
