title: How to clear static variable value and assing new
body: <p>I am calling an aspx website from my MVC project and passing two parameters</p>
  
  <p>In Global.asax at Session_start I am assigning this parameters to two static variables</p>
  
  <pre><code>protected void Session_Start(object sender, EventArgs e)
          {
  
              global.c = Request.QueryString["C"];
              global.u = Request.QueryString["U"];
  
          }
  </code></pre>
  
  <p>there is no logout in this aspx website.
  First time the values are assigning correctly which is passing from the MVC
  but for the next request it is showing the old values.</p>
  
  <p>eg: <a href="https://www.xxxxxx.com/aa.aspx?C=2&amp;U=2" rel="nofollow">https://www.xxxxxx.com/aa.aspx?C=2&amp;U=2</a></p>
  
  <p>This time it will show 2 and 2</p>
  
  <p>next time if i call <a href="https://www.xxxxxx.com/aa.aspx?C=32&amp;U=14" rel="nofollow">https://www.xxxxxx.com/aa.aspx?C=32&amp;U=14</a></p>
  
  <p>it will retain the 2 and 2.
  Since there is no logout i can't use</p>
  
  <pre><code>System.Web.Security.FormsAuthentication.SignOut();
  </code></pre>
  
  <p>since session will active for 20min default this value will be there..</p>
  
  <p>How can i store these paremeter globally in aspx and use over all the pages.</p>
  
  <p>Simeltaneously multiple user can access this aspx page with different parameters.</p>
