A peace of the web.config :
<authentication mode="Forms">
   <forms name=".ASPXLOGIN" loginUrl="~/Member/Login.aspx" enableCrossAppRedirects="false"/>
</authentication>

You have an IIS, then behind, you have many web applications, you only need one LoginModule.NET to manage users authentification in those applications.
In your applications just use the same forms name ans set enableCrossAppRedirects to true.
Try it is amazing.
