Unknown Error when cookieless="UseUri" in web.config

I am also struggling with this, please post if you managed to resolve it!!!

The setting "UseUri" is another way of telling ASP.NET not to use cookies to manage sessions. When cookies are not used for session management, ASP.NET embeds the session identifier within the URI of each inbound request. Those are the "stray/random" characters you see in what you posted - the web server, and then, ASP.NET, will parse that data from the string and use that to track the session rather than via a client-side cookie.

If your application is not working with cookieless="UseUri" or "true," it would suggest that there is a problem with the way the application handles the "mangled" URL's that contain the session information.

I hope that helps.

Hello everybody,

I have just found resolution for that problem.

In my web.config:

<sessionState timeout="45" cookieless="true">
</sessionState>

In .aspx file:

<CKEditor:CKEditorControl ID="txtAdHocTemplateContent" runat="server" />

In .aspx.cs file:

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);
        CKFinder.FileBrowser fileBrowser = new CKFinder.FileBrowser();
        
        string cookielessUrl = Context.Items["AspCookielessSession"] != null
                                   ? string.Format("(S({0}))/", Context.Items["AspCookielessSession"])
                                   : string.Empty;

        string appUrl = string.Format("{0}/", Context.Request.ApplicationPath).Replace(@"//", @"/");

        fileBrowser.BasePath = string.Format("{0}{1}ckfinder/",
                                             appUrl,
                                             cookielessUrl);

        fileBrowser.SetupCKEditor(txtAdHocTemplateContent);
    }
