Specifying master page in Web.config causes every content page to inherit from the master page

 
<configuration>
    <system.web>
        <pages masterPageFile="~/Default.master" />
    </system.web>
</configuration>
 
Once specified in this manner, the content page"s Page directive can then be : 
<%@ Page Language="VB" %>
You can override the application-wide master page specification by 
declaring a different master page within your content page:
<%@ Page Language="VB" MasterPageFile="~/MyOtherCompany.master" %>



Specifying the master page for a specific folder in the Web.config file: Use <location>

<configuration>
    <location path="AdministrationArea">
        <system.web>
            <pages masterPageFile="~/yourMaster.master" />
        </system.web>
    </location>
    
</configuration>
