How do you cache a json file?

Hi @ljvd, after you turned ON LiteSpeed Cache Settings > Cache > Cache REST API, wp-json will be cached automatically. You do not need to tune any .htaccess file manually.

Thanks for this prompt answer @stanleylitespeed

Unfortunately, it isn’t about wp-json, it is a json file generated by a PWA plugin.
Have you some tip about how to cache a specific file?

Hi @ljvd, can you show me the link of the JSON response?

@stanleylitespeed
The file that I Would like to cache is here
https://www.ljvd.com/superpwa-manifest.json
It’s mostly a static file …

If it’s a static file, it does not need to be cached because it’s already serving as the highest speed response without any backend PHP processing. So our plugin will not cache this type of file.

Thanks for the explanation, so your service isn’t appropriate for providing a cached delay for static files …

Could you explain more about the cached delay for static files?

The file is without expiration date header.
If I set up it in the excusion tab as Force URL caching
/superpwa-manifest.json$ 604800
Despite a total cache purge both with litespeed and by bunnyCDN, that changes nothing …

It’s mostly a GTMatrix challenge with few local webmasters, GTMatrix clames:
Leverage browser caching for the following cacheable resources:
https://www.ljvd.com/superpwa-manifest.json (expiration not specified)

It now fixed with some hard directive, but it’s weird …
Here is the patch

<IfModule mod_expires.c>
	<Files superpwa-manifest.json>
        ExpiresActive On
        ExpiresDefault "access plus 1 month"
	</Files>
</IfModule>

Thank you for sharing this.
