Accessibility: Read/Write
Specifies whether the site will use the minimal download strategy by default.<127>
The minimal download strategy will use a single .aspx file (start.aspx) for your pages, with the actual URL encoded in the text following the hash mark ('#'). When navigating from page to page, only the changes between two compatible pages will be downloaded. Fewer bytes will be downloaded and the page will appear more quickly.
