Welcome to the ASP.NET forum.
Is the session being saved in both server and client side in this case
In ASP.NET; you have a Session cookie. This cookie is used to identify which session is yours; but doesn't actually contain the session information.
By default, ASP.NET will store session information in memory inside of the worker process (InProc), typically w3wp.exe. There are other modes for storing session, such as Out of Proc and a SQL Server.
