title: Change session variable and reload page in ASP.NET
body: <p>I'm using ASP.NET MVC for some database queries and have a session variable that selects which part of the database the queries should use. Now I want to have a dropdown menu on each page that allows changing the session variable. After changing it, the current page should be reloaded and use the new value.</p>
  
  <p>Now I could implement this for each action on my controllers, but I would prefer a more general approach. My idea was to change the session variable and then reload the page the user was on when he clicked the option in the dropdown menu.</p>
  
  <p>How do you implement something like this in ASP.NET?</p>
