I have some pages that are sent via HTTPS. Internet Explorer sometimes complains about “This webpage contains content that will not be delivered using a secure HTTPS”.
I looked in the html source to confirm all content calls (href, src, etc…) are sent via https. My CSS files use relative paths. But I’m still getting these warnings.
Is there an easy way to track down which items are not sent via HTTPS?
I usually use Firefox + Firebug (the “Net” tab) to find the offending request. You could also use Fiddler for this. (with any browser)
