How to trace source of IE8 Security Warning?

问题:

I am getting the dreaded security warning when running my GWT web app under IE8: "this webpage contains content that will not be delivered using a secure HTTPS"

It of course works fine with Firefox and Chrome.

I have taken a look at the requests with firebug and I see no HTTP requests.

I have also used both Fiddler and HttpWatch with IE and I still see no HTTP requests.

Can anyone provide me with some clues as to what else might trigger this warning?

There are certain snippets of Javascript that can also cause a problem. Please see:

Also, have a look through the pile of comments on:

Some of the commenters have found and fixed other causes of the warning too.
