Sub-Template

        <p>
        To register a sub-template, you include a register directive in the master template. You can include as many Register directives as you like, so one master template can include multiple sub-templates. Sub-templates can be nested.

Improving the Performance of a Reusable Authorization Framework

        <ul>
        <li>
        Batch authorization queries whenever possible to avoid frequent out-of-process
        round trips. For example, retrieve roles for multiple users in a single request.
        </li><li>
        Cache the authorization data close to where you will use it with an in-memory
        store, such as a Hashtable. The cache also reduces dependencies on the location
        and organization of the underlying store. You might also want a separate cache
        for each physical computer, for performance and increased security.
        </li><li>
        Implement scheduled or on-demand refreshes of the cache information.
        </li><li>
        Implement lazy initialization of the authorization cache to avoid retrieving
        authorization information when no access checks will occur.
        </li>
        </ul>

How to Change the Principal in an ASP.NET Application

protected void Application_AuthenticateRequest(Object sender, EventArgs e)
{
   // Check whether there is a current user and that
   // authentication has occurred.
   if (!(HttpContext.Current.User == null))
   {
      IIdentity CurrentUserIdentity = HttpContext.Current.User.Identity;
      // Check to see whether the Principal was cached.
      string CachedPrincipalKey = "CachedPrincipal" + id.Name;
      if (HttpContext.Current.Cache[CachedPrincipalKey] == null)
      {
            // Load the principal by calling the GetPrincipal method.
            HttpContext.Current.Cache.Add(
            CachedPrincipalKey,
            GetPrincipal(CurrentUserIdentity),
            null,
            DateTime.MaxValue,
            new TimeSpan(0,30,0),
            CacheItemPriority.Normal,
            null);
      }
      HttpContext.Current.User = (IPrincipal)
      HttpContext.Current.Cache[CachedPrincipalKey];
   }
}
