Sorry, I didnt mention that I am trying to use purchased webfonts, which I have downloaded and installed in a local folder, as suggested in http://support.livemeshthemes.com/faqs/install-custom-fonts/.
When installed in a local folder, the post suggests to use the url as http://coursible.com/i/{folder}. This url is the one that works for only either http or https, and I would like to be able to use for both.
