HttpContext.Current.Response.Redirect is trying to send users to the wrong place

问题

I've got a section of code that redirects users to a page when their session times out:

void Session_Start(object sender, EventArgs e) 
{
    // Code that runs when a new session is started
    string szCookieHeader = HttpContext.Current.Request.Headers["Cookie"];
    if ((null != szCookieHeader) && (szCookieHeader.IndexOf("ASP.NET_SessionId") >= 0))
    {
        HttpContext.Current.Response.Redirect("SessionTimeout.aspx");
    }
}

The problem is that IIS can't find SessionTimeout.aspx because its looking in the wrong place:

The file '/site/site/site/site/site/site/Site/SessionTimeout.aspx' does not exist.

With more and more "/site/" levels being added as time goes on. I can suppress the problem by creating a tree of ".../site/site/..." and placing an SessionTimeout.aspx in each but this is obviously not a true solution.

Does anyone know what's going on?

回答1:

Have you tried to use ~ ?

HttpContext.Current.Response.Redirect("~/SessionTimeout.aspx");

that will be resolved at runtime with the full url of your site.

回答2:

Your redirect is relative to the current page. Add ~/ to the url to have it look at the root of the site.

Your redirect should read:

 HttpContext.Current.Response.Redirect("~/SessionTimeout.aspx");
