How to create a text file from a string and open it in new tab in asp.net?

I want to create a text file from a string and send it to browser's new tab on a button click in aspx page. The file must be created on the fly and should not be stored anywhere on server.

Currently, I am able to send the file on the same tab by attaching the file in the http response and sending that response to browser.

unfortantly, due to popup blockers, creating a tab really not going to work these days.

However, you can on the same page, say a button click, and then "fake" the same thing as if the user did navigate to a simple text document.

This code will work:

Protected Sub cmdJump_Click(sender As Object, e As EventArgs)

    Dim strBuf =
        "First line of text" & vbCrLf &
        "Seond line of text" & vbCrLf &
        "Third line of text"

    Dim strFakeFileName As String = "mytext.txt"
    Dim strConType = MimeMapping.GetMimeMapping(strFakeFileName)

    Response.Clear()
    Response.ContentType = strConType
    Response.AppendHeader("Content-Length", strBuf.Length)
    Response.AppendHeader("Content-Disposition", "inline; filename=" & strFakeFileName)
    Response.Write(strBuf)
    Response.End()

End Sub

As noted, this will occur on the current page. User can hit back button.

However, opening a new tab? Modern browsers just don't allow this with much success.
