Ever had a perfectly “safe” page or file turn into an attack vector out of nowhere? That can happen when browsers start guessing what your content is instead of listening to your server.

If you want a faster WordPress site, caching belongs at the center of your performance plan. It reduces the work your server has to do and turns slow, dynamic page builds into quick, static responses.
