I'm dynamically generating images as well as json data and I've tried setting Cache-Control: public, max-age={maxAge} but I'm noticing in all responses an absence of the CF-Cache-Status header. The getServerSideProps takes a context parameter which is an object containing keys like params, req, res, query etc. Svelte is a modern reactive component framework that runs at build time, converting components into highly efficient imperative code that surgically . .
