On a new Kirby 3 installation I updated index.css on the server. Yet, however much I afterwards emptied the browser cache, developer tools in Safari and others were still showing my old CSS - although I checked that the file on the server was indeed the updated one.
Even when I deleted index.css on the server, all browsers (with empty cache) were unwavering and went on showing the deleted CSS file.
My question is: It might well be that I am overlooking something here - but I had the idea that perhaps Kirby is still caching my old CSS. Is that possible, and, if so, where could I empty the cache?
I just checked, and, all too true, the web server is using ‘Varnish-Cache’.
You have to explicitly disable it via htaccess in each directory where you don’t wish to have it. After adding htaccess to my assets/css everything is back to normal.
