 * I have set up WP rest cache with woocommerce endpoints with instruction found
   on the forum, but it doesn’t cache the request that return an empty list. For
   example, if I call /wp-json/wc/v3/products/?order=asc&page=1&category=211&per_page
   =15&status=publish&orderby=title, it will serve a cached result, but for /wp-
   json/wc/v3/products/?order=asc&page=2&category=211&per_page=15&status=publish&
   orderby=title, it will never cache the request. I did some test and it seems 
   consistent that when the result is a json empty set [], the request is not cached.

 * Checking the code, [we explicitly don’t cache empty result](https://github.com/acato-plugins/wp-rest-cache/blob/e7c26135b2e242ebb180dc75f81d669ac742adc3/includes/api/class-endpoint-api.php#LL253C6-L253C6).
   Why is it so?

 * Hi [@mjulien](https://wordpress.org/support/users/mjulien/)
 * Thank you for using our plugin!
   Good question, we explicitly do not cache empty
   result sets, because in our experience this is an unwanted situation and often
   even an error.I have seen your pull request and I think it is a good idea to 
   implement a filter like that. Unfortunately at this moment I do not have time
   to review and test it and to deploy a new version. I will get back to you but
   that will not be this or next week.
