How to integrate OS Application with ASP.NET Web Application (using membership)

How to integrate OS Application with ASP.NET Web Application (using membership)

  
There is an ASP.NET project completed. The company where I work asked a module of this project in OutSystems.

How do I integrate the two projects (ASP.NET and OS) using "membership"?

Goal is that the user only accesses the OS page if he is logged ASP.NET application.

Thanks!!!!
 

I'd like to know if it's possible modify the web.config of my OS application to use the resource of "membershipt" that belongs to a concluded  project ASP.NET.

My objective is validate the users's access to my OS application. You can only access the web page OS, if the user is connected to the ASP.NET project. The OS page would receive some parameters and use them to validate the user using features of "membership".

Questions:

1 - Is possible receive parameters of one Web  ASP.NET project?

2 – Is possible to hold two separate sessions (OS Application and ASP.NET Application) ?
