ASP.NET Set a Global constant variable?
<p>Working on the Loginmechanism... But got problems..</p>

<p>I have a UserControl (<code>LoginUserControl.ascx</code>) placed on a <code>Default.aspx</code>, which is in my Masterpage(<code>Site.Master</code>)...
Over the UserControl, the User can login... 
Now I would like to set a <strong>global Variable</strong>, which won't change its Value, wherever I navigate...</p>

<p>A Variable like, <strong>IsLogged, (true/false)</strong>.
Because I got problems with Viewstate and when I change an other Site (by Example to <code>MyOtherSite.aspx</code>), IsLogged is then <strong>false</strong>...</p>

<p>How can I do it?</p>
