I'm wondering if this is the right behavior.
As I have the fonts in the stylesheet base64 encoded I'm still seeing multiple requests with 0 bytes.
@font-face {
font-family: 'Open Sans';
font-style: normal;
font-weight: 400;
src: local('Open Sans'), local('OpenSans'), url('data:application/x-font-woff;base64,ENCODED_STRING') format('woff');
}
