Na installatie kreeg ik deze mail; handig om hier te bewaren. Het hangt van de server af of dit goed werkt. Geen probleem bij hosting2go.

Leverage Browser Caching is a very natural and very simple fix that does not cause problems with your website. All browsers use it and almost every server uses it. The reason that it will sometimes fail is based on your server’s restrictions. The reason you probably installed this software in the first place is because of your website seeming slow or sluggish – we understand. Ours was too.
