Is there anybody who knows why the following request (xml in the example, but valid for every download file type request) works in the on-line example but locally [ this.Response.End() ] returns always a [BADRESPONSE: Unexpected token <] ?
Could it be releated with app/web server configuration or something missed?

I'm referring, for instance, to example

https://examples2.ext.net/#/GridPane...l_Data_Paging/

    
protected void Store1_Submit(object sender, StoreSubmitDataEventArgs e)
    {
        XmlNode xml = e.Xml;

        this.Response.Clear();

        string strXml = xml.OuterXml;
        
        this.Response.AddHeader("Content-Disposition", "attachment; filename=submittedData.xml");
        this.Response.AddHeader("Content-Length", strXml.Length.ToString());
        this.Response.ContentType = "application/xml";
        this.Response.Write(strXml);

        this.Response.End();
    }

Thanks and bye
