I will assume for the purposes of this article, that you have control over your hosting server and are able to install the necessary add-ons and make configuration changes to Apache and PHP. If you are on a shared environment, you may have to check with your hosting support if you can apply the tips from this article. But, you know that you should at least be on a VPS if you are running Magento.

We’ll discuss the most basic directives in this article.
