The export works well with Firefox, however when I tried it with IE 7, I get an error stating:

Internet Explorer cannot download default.aspx from 'My Domain Name'

Internet Explorer was not able to open this Internet site.The request site is either unavailable or cannot be found. Please try again later.

Please advise.

Thanks

Here is my code

Public Shared Sub Export(ByVal fileName As String, ByVal gv As GridView)
        HttpContext.Current.Response.Clear()
        HttpContext.Current.Response.AddHeader("content-disposition", String.format("attachment; filename={0}", fileName))
        HttpContext.Current.Response.ContentType = "application/ms-excel"

        Using sw As New StringWriter()
            Using htw As New HtmlTextWriter(sw)
                ' Create a form to contain the grid
                Dim table As New Table()

                ' add the header row to the table
                If gv.HeaderRow IsNot Nothing Then
                    TRUtilities.PrepareControlForExport(gv.HeaderRow)
                    table.Rows.Add(gv.HeaderRow)
                End If

                ' add each of the data rows to the table
                For Each row As GridViewRow In gv.Rows
                    TRUtilities.PrepareControlForExport(row)
                    table.Rows.Add(row)
                Next

                ' add the footer row to the table
                If gv.FooterRow IsNot Nothing Then
                    TRUtilities.PrepareControlForExport(gv.FooterRow)
                    table.Rows.Add(gv.FooterRow)
                End If

                ' render the table into the htmlwriter
                table.RenderControl(htw)

                ' render the htmlwriter into the response
                HttpContext.Current.Response.Write(sw.ToString())
                HttpContext.Current.Response.[End]()
            End Using
        End Using
    End Sub

The above code works fine with Http and Https for Firefox. It doen't work in IE for Https.
