Proper setting of expire headers for fonts-CodePudding

Following old advices here and here I'm curious what is the proper syntax for APACHE server:

AddType font/woff2 .woff2 
ExpiresByType font/woff2 "access plus 1 year"

AddType application/woff2 .woff2 
ExpiresByType application/woff2 "access plus 1 year"

Did you include the ExpiresActive on?

<IfModule mod_expires.c>
  ExpiresActive On
  AddType font/woff2 .woff2 
  ExpiresByType font/woff2 "access plus 1 year"
</IfModule>

I am using something like these:

<IfModule mod_expires.c>
  ExpiresActive On
  ExpiresByType image/x-icon "access plus 2592000 seconds"
  ExpiresByType image/jpeg "access plus 2592000 seconds"
  ExpiresByType image/png "access plus 2592000 seconds"
  ExpiresByType image/gif "access plus 2592000 seconds"
  ExpiresByType image/svg "access plus 2592000 seconds"
  ExpiresByType application/x-shockwave-flash "access plus 2592000 seconds"
  ExpiresByType text/css "access plus 2592000 seconds"
  ExpiresByType text/javascript "access plus 2592000 seconds"
  ExpiresByType application/x-javascript "access plus 2592000 seconds"
</IfModule>

It's not really a question of "syntax". Both your examples use the same "syntax". But rather, what is the correct/official mime-type (that user-agents understand).

The official mime-type according to the WOFF2 spec (W3C Recommendation / 1-March-2022) is:

font/woff2

This was initially discussed in the WOFF File Format 2.0 - W3C Working Draft 14 April 2015 - Appendix A: Internet Media Type Registration

AddType application/woff2 .woff2

I don't think application/woff2 has ever been a (proposed) mime-type? The IANA Media Types initially defined application/font-woff for woff font files, so by extension you could assume that application/font-woff2 would be used for woff2, but I don't see this documented anywhere? And IANA have since "deprecated" application/font-woff in favour of font/woff and list only font/woff2 for woff2 font files.

AddType font/woff2 .woff2

You shouldn't need to manually add the AddType directive here. Providing you are using a relatively recent distro of Apache then the mime.types file that is imported (using the TypesConfig directive) during startup already includes the necessary (and correct) mime-type for .woff2 files:

font/woff2                  woff2
