Response redirect target blank

Problem:
Repsonse.Redirect cannot open the url in "target blank" mode

Solution:
javascript,
for example: Response.Write("<script language='javascript'> window.open('" + DropDownList.SelectedValue + "', 'window');</script>");

from jose:
 
Response.Write("<script type='text/javascript'>");
        Response.Write("document.location = 'http://www.google.com';");
        Response.Write("</script>");
        Response.End() ;
