Internet Explorer Mixed Content Warning


My SharePoint WebSite is http protocol.
The reverse proxy is https (http://mywebsite is redirected to https://mywebsite).
In Internet Explorer, everytime I click on a item of the treeview, I get the IE Mixed Content Warning :
"Do you want to view only the webpage content that was delivered securely? The webpage contains content that will not be delivered using a secure HTTPS connection, which could compromise the security of the entire webpage."
I noticed that the url of the folder icons are both http and https (see attach file fot the screenshot).
The alert disappears if the option « Display Mixed Content » is set to « enable ».
But The WebSite is used by a hundred of persons and we can’t ask them to change this option.
Is there a way to avoid the alert without changing the « Display Mixed Content » option ?
