How Can I Redirect To Another Page After The PDF Report Downloaded?

When I click the link to download the report in web page, it can pop up a window so that let me "open" or "save". After I open or save this (.pdf) file, I want to auto redirect to another web page. Can I do that? Here is my code:

Response.AddHeader("Content-Disposition","attachment;filename="" + getExportFilename() + """);
Response.ContentType = "application/octet-stream";
byte[] result = rs.Render(TLOWebRptFunc.GetSaveReportPath(this.Context), TLOWebRptFunc.GetReportType(this.Context), null, "<DeviceInfo><Toolbar>False</Toolbar></DeviceInfo>", wparam, credentials, null, out encoding, out mineType, out wparam, out warnings, out streamIDs);
Response.BinaryWrite(result);
Response.End();
