Why does /_layouts/15/start.aspx appear as part of my SharePoint 2013 Site URL ?

The URL path of a newly created site collection will include “/_layouts/15/start.aspx” To avoid this it is necessary to deactivate the following site feature:

1. Go to Site Settings – Site Features page.

2. Deactivate the “Minimal Download Strategy” feature.

Why is the Minimal Download Strategy available by default on various site collection templates including the Team Site? This is a new feature for SharePoint 2013 that is designed to increase the performance of the SharePoint site.

The start.aspx page has a specific JavaScript object asyncDeltaManager (defined in start.js). This parses the URL, looks for the # sign and takes the path following that and dynamically loads that page.

Subsequent requests to pages are dynamically loaded through the asyncDeltaManager object. Once a link is clicked it will invoke a method in the JavaScript object which creates the MDS URL and appends the query string parameter AjaxDelta=1. A request is created and downloaded asynchronously and only the “delta” is returned to the client and assembled and rendered using JavaScript.
