Multiple content pages & ASP.net membership.

Hi,

I have been looking over the web but I can not find what I am looking for.  I wonder if you can provide me resources on this type of topic and I can read up and learn more about it.

Here is my scenario:

I have a main master page with 2 content place holders with content pages in them.

In content page 1:  I want to put in the login control
In content page 2: I want to eventually display the content once the user authenticated.

I plan to use the .NET membership.  When I look up on MSDN they have great examples but they are done in one single page or content page only.  

So can you show me how can I handle session variable ect... across multiple place holders?  If a user logged in successfully in content place holder 1, how can content place holder 2 be authenticated as well?

Any direct example or resources are great.
