Caching 204 status code

[nfn]

Hi

I have this in .htaccess

ExpiresByType image/x-icon A2592000

And in the rewrite conf I have setup this rule:

RewriteRule favicon\.ico$ - [L,R=204]

I was expecting that favicon would be cached, but is not.

Is the status code is 200, the .ico file os cached.

What do I need to do to make 204 status code cacheable?

Thanks

Hi @nfn ,

It is cached by default, you don't need to set a cache rule for it.

### marker FAVICON start ###
RewriteRule favicon\.ico$ - [E=cache-control:max-age=86400]
### marker FAVICON end ###

Best,
Eric

Hi @Cold-Egg

I'm behind Cloudflare with cache everything and neither Litespeed header (directly) neither Cloudflare caches 204 responses.
Cf-cache-status is always miss.

If I set response header to 200 favicon is cached, so looks like 204 responses are not cacheable.

Related to LS Wordpress Cache plugin, there is something I would like to understand.

In .htaccess all static files (images/js/css/ico) have 2592000 seconds cache, but headers show 604800
Where does this came from?

Because your browser cache is handled by server level.

If you are a server admin, you have somewhat more control. In the LiteSpeed Web Server Admin, navigate to Server > General and scroll down to Expires Settings.
