Since upgrading to the new AjaxControlToolkit version (July 2013 Release) streaming of Excel files to the browser has stopped working.
This worked perfectly on older versions of the AjaxControlToolkit (last version I used was 3.031106.0)
I'm basically writing the HTML of a GridView to Response as below;
```
Response.Clear()
Response.AddHeader("content-disposition", "attachment;filename=myexcelsheet.xls")
Response.Charset = ""
Response.ContentType = "application/vnd.xls"
Dim stringWrite As System.IO.StringWriter = New System.IO.StringWriter()
Dim htmlWrite As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite)
paycalc_GridView.RenderControl(htmlWrite)
Dim d As String = ""
Response.Write(stringWrite.ToString())
Response.End()
```
Comments: We're seeing the same problem with IE6/IE7/IE8 file downloads over HTTPs, even using the Dec 14, 2013 build of AjaxControlToolkit. Did anyone find a resolution to this problem?
