 /**
 23  
  * Contains code needed to render the <base> tag for pages. The <base> tag ensures that
 24  
  * the base URL for the rendered page matches the location of the page template in the servlet
 25  
  * context, so that relative URLs to static assets (images, stylesheets, etc.) will be processed
 26  
  * correctly. This is important starting with release 4.0, where HTML templates are no longer
 27  
  * restricted to the servlet root.
 28  
  * <p>
 29  
  * Note that pages outside of the application namespace (provided by the framework itself, or in a
 30  
  * library) are "virtually located" in the application root.
