Hosting #79

Compress the HTML output

You can compress the content of HTML pages to minimize bandwidth consumption between the client and the server. All modern browsers (for smartphones, tablets, notebook and desktop computers) accept HTML compressed via gzip or Deflate. The easiest way to do so is to configure the web server so that it compresses the HTML data stream, either on-the-fly or automatically, as it leaves the server. This practice (on-the-fly compression) is only beneficial for a HTML data stream as it is constantly evolving. When possible, we recommend that you manually compress static resources (e.g. CSS and JavaScript libraries) all in one go.
