Why ASP.NET kills my background thread?

Question

I have the following code in my codebehind (aspx.cs):

protected void button1_Click(object sender, EventArgs e)
{
    new Thread(delegate() {
        try

Providing another solution: you don't need to set your page with the async property. The following code will work fine:

new Thread
(
    delegate()
    {
        try
        {
            MyMethod(myVar);
        }
        catch (Exception ex)
        {
            // handle
        }
    }
)
{
    IsBackground = true
}.Start();

In this code, IsBackground = true is what prevents the thread to be aborted when the request finishes.
