File Expiration Times

tfh

I have the following File Expiration Times set:

but I still see quite a lot of requests for for example the font & CSS files which stil get fully answered (http code 200) in my log. Am I doing something wrong here?

I just visited https://www.arnauddeklerk.com/about/ and all the files have a 30-day expiration date (HTML, CSS, JS, JPG, PNG, WOFF2).
You may want to move the catch-all MIME type to the last position in the list so the other items get priority over it.
BTW, You can load up Chrome, press F12 to load the DevTools. Click the "Network" tab and navigate the browser window to your site. The Network tab will be populated with the web requests. Click one of them to see the headers sent by your site. This will help you quickly confirm whether your settings are being transmitted correctly.

Browsers are not forced to perform HTTP content negotiations. They can bypass caching and choose to get a new copy.
