I am trying to allow anonymous users to an entire directory instead of listing each file in my Web.config

Here's the current method:

 <location path="ViewPage.aspx">
  <system.web>
   <authorization>
    <allow users="*" />
   </authorization>
  </system.web>
 </location>

Instead of listing each page like this, what is the code to list the directory?  The folder containing the Web.config file is called MainDir.  It contains the folder, AnonDir, which houses all of the files I wish to make available to anonymous users.  Do I type, MainDir/AnonDir as the location path?  Any help with this is greatly appreciated.
