Access Session variable of ASP.Net solution into MVC project

Question

Hi,
I have an old website created in VS 2008 i have migrate it into new framework VS 2012.
Now i have a new request to create a module in MVC but inside same solution. I have created a new MVC project inside same solution but i have following issues -

My default login into website is available in my traditional website (old) and i need to access the Session variable into my newly created project which is in MVC.

So how can i achieve it to navigate to MVC website and access same Session variable inside it.
