com.samskivert.servlet.SiteResourceLoader
Web applications may wish to load resources in such a way that the site on which they are running is allowed to override a resource with a site-specific version (a header, footer or navigation template for example). The site resource loader provides this capability by loading resources from a site-specific jar file.
The site resource loader must be configured with the path to the site-specific jar files, the names of which are dictated by the string identifiers returned by the {@link SiteIdentifier} provided to theresource loader at construct time. For example, if the configuration dictates that site-specific jar files are located in /usr/share/java/webapps/site-data and the site identifier returns samskivert as the site identifier for a particular request, site-specific resources will be loaded from /usr/share/java/webapps/site-data/samskivert.jar.
