Do browsers download Icon Fonts (like FontAwesome) for every page-load?
I'm unable to determine whether the icon fonts like FontAwesome are downloaded to user's computer every time they visit a new website. I'm aware of 'browser cache' - but not sure if the browser must download the font again while visiting a new website.
My best guess so far is that if the user has earlier visited any site that uses FontAwesome, they'll have the font downloaded on the browser. So, the browser need not download it again; but how can we be sure that the fonts aren't getting downloaded?
PS: I'm working on minimizing the total count of http requests made to the server (with an aim to reduce the page fetch timing).
