In Aspose.Excel I used to be able to do
myExcel.Save("report.xls", SaveType.OpenInExcel, FileFormatType.Excel97, this.Response);
and this worked on both HTTP and HTTPS
After upgrade to Cells This doesn't work over HTTPS anymore(in IE6). Is there workaround for this problem? It did work before!
P.S. It looks like your PDF team had similar problem and was able to fix it: http://www.aspose.com/Community/Forums/16420/ShowPost.aspx
