If you use your own CSS file with your own CSS fonts, then we’ll notice that Sharepoint doesn’t send cache headers if you use the below CSS code:
1 2 3 4 5 6 7 8 | @font-face { font-family: 'Roboto'; src: url('/_catalogs/masterpage/css/fonts/Roboto/Regular/Roboto-Regular.woff2') format('woff2'), url('/_catalogs/masterpage/css/fonts/Roboto/Regular/Roboto-Regular.woff') format('woff'), url('/_catalogs/masterpage/css/fonts/Roboto/Regular/Roboto-Regular.ttf') format('truetype'); font-weight: 400; font-style: normal;} |
To have this resource sent back from the Sharepoint server with cache headers, you just need to add ?ctag=0 at the end:
1 2 3 4 5 6 7 8 | @font-face { font-family: 'Roboto'; src: url('/_catalogs/masterpage/css/fonts/Roboto/Regular/Roboto-Regular.woff2?ctag=0') format('woff2'), url('/_catalogs/masterpage/css/fonts/Roboto/Regular/Roboto-Regular.woff?ctag=0') format('woff'), url('/_catalogs/masterpage/css/fonts/Roboto/Regular/Roboto-Regular.ttf?ctag=0') format('truetype'); font-weight: 400; font-style: normal;} |
