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

   <source lang="csharp">


<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" %> 

</source>


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

   <source lang="csharp">

<configuration> 

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

</configuration> 

</source>
