Is there already a .htaccess on server? If you want I can add one to get better cache results by using cache-control header.

Is still needed and growing in relevance for the performance of the PWA. At the moment only score 84 from 100. Its just about caching. Should be done easily by adding a matching .htaccess file with static cache rules.
