Lcov website differs betwen HTTP and HTTPS
I noticed this when visiting the link from the devcentral webpage.
When you click on the link, you get redirected to https://lcov.libreoffice.org. That site seems to run an old version of the devcentral code itself.
If you click the image, you get redirected to http://lcov.libreoffice.org. This website is the correct one.
The issue that the image and link give different href is out of scope for this issue. I'll try to submit a patch through Gerrit for it.
But I image that the http and https versions of the same URL should have the same page.
