Auto prefetch URLs and preload

Hi,
first of all, if you are running an woocommerce website, chances are you cannot use the prefetch option, especially the prefetch on hover option. Cause in that case if someone hover on the add to cart button things might get added onto the cart. So, you can try enabling the option and testing on your website how it is performing.

Preloader is something I generally do not recommend anyone enabling at this point as it requires good about of server resource and Cloudflare doe3sn’t always cache the requests.

Prefetch: In this case when when someone hove on some internal link or the page is loaded (based on whatever option you have enabled), the browser sends a prefetch request to the servers prefetching the webpage beforehand, So when an user actually clicks on the link, it loads instantly.

Preloader: It uses cURL to fetch different URLs of the website, hoping Cloudflare will see these fetch requests and cache the contents. But currently CF system have gotten very smart and unless you are sending request from an actual browser, they tend not to cache items.
