			<h1>Scroller example <span>Server-side processing (5,000,000 rows)</span></h1>

			<div class="info">
				<p>DataTables' server-side processing mode is a feature that naturally fits in with Scroller perfectly.
				Server-side processing can be used to show large data sets, with the server being used to do the data
				processing, and Scroller optimising the display of the data in a scrolling viewport.</p>

				<p>When using server-side processing, Scroller will wait a small amount of time to allow the scrolling
				to finish before requesting more data from the server (200mS by default). This prevents you from DoSing
				your own server!</p>

				<p>This example shows Scroller using server-side processing mode and 5 million rows.
				<strong>Important</strong> This particular example uses <a href=
				"//datatables.net/reference/option/ajax"><code class="option" title=
				"DataTables initialisation option">ajax<span>DT</span></code></a> as a function to 'fake' the data to
				show Scroller's ability to show large data sets. It does not have a real database behind it! You would
				normally not use <a href="//datatables.net/reference/option/ajax"><code class="option" title=
				"DataTables initialisation option">ajax<span>DT</span></code></a> as a function to generate data, but
				rather as a url for where to fetch the real data!</p>

				<p>In this example we also enable the <code>loadingIndicator</code> option of Scroller to show the end
				user what is happening when they scroll passed the currently loaded data.</p>
