Q:

HTTPS and RSS feeds.  Why are they only HTTP? 

My checkout page isn't 100% secure, and it's because of my RSS feeds.   When I go to my page with HTTPS, everything loads with HTTPS (css files and stuff),  EXCEPT for RSS feeds.  They still load with HTTP. 
Is there a way to get Magento to use HTTPS with RSS links?   

A:

Please review this post that goes over the various methods of finding insecure content on a page as a simple URL would not cause an insecure content error.  Assets such as css, images, js and others will.  As well as insecure content pulled through those assets such as inside javascript source.
