title: What is gZip compression?
body: <p>I have heard a lot that one should use <strong>gZip</strong> for their webpages for faster access and downloads, and that it also saves the bandwidth.</p>
  
  <p>So what is this gZip compression and how does it make the downloads faster ? Does it compress the HTML and images or just the HTML.</p>
  
  <p>If I am to start using gZip in my webapps what <strong>considerations</strong> do I need to make ?
  Are there any server or browser <strong>restrictions</strong> for it, or does it support a particular encoding only.</p>
