Enforcing web.config authorization entries

Question

Ultimate goal is to provide protection against programming mistakes. I want to make sure that every page in a portion of my web application has a role specified like below. Ideally I would like to programatically check all requests coming in ( think IHttpModule ) and make sure that the page being requested has a role specified.

I can't seem to find how to get programatic access to the allowed roles.

<location path="foo.aspx">
 <system.web>
  <authorization>
   <allow roles="modifier"/>
  </authorization>
 </system.web>
</location>

Answer 1

make a deny * in the root, so every page is not allowed, until it is explicitly activated....

Answer 2

Stumbled across this AuthorizationRuleCollection.

From MSDN, I've not tried it as I solved my problem using a tecnique similar to the AuthorizeAttribute in the MVC framework.

System.Configuration.Configuration configuration = WebConfigurationManager.OpenWebConfiguration("/aspnetTest");
AuthorizationSection authorizationSection = (AuthorizationSection)configuration.GetSection("system.web/authorization");
