force download of remote file

Many times we want 2 enable 2 users to download files from our web site
just put this function in the Page_Load function and then the users will be enable to download remote files from any web site (note that the function parameter is a virtual path!):

private void forceDownloadRemoteFile(string sFileVirtualPath)
{
    string sFileName = System.IO.Path.GetFileName(sFileVirtualPath);
    WebClient oWebClient = new WebClient();
    MemoryStream oMemoryStream;
    try
    {
        byte[] bytes = oWebClient.DownloadData(sFileVirtualPath);
        oMemoryStream = new MemoryStream(bytes);
    }
    finally
    {
        oWebClient.Dispose();
    }
    BinaryReader oBinaryReader = new BinaryReader(oMemoryStream);
    Response.Clear();
    Response.ContentType = "application/octet-stream";
    Response.AddHeader("content-disposition", 
        string.Format("attachment;filename={0}", sFileName));
    Response.BinaryWrite(oBinaryReader.ReadBytes((int)oMemoryStream.Length));

    oBinaryReader.Close();

    Response.Flush();
    Response.End();
}

To execute this function u can use this code:

protected void Page_Load(object sender, EventArgs e)
{
    string sFileVirtualPath = @"http://localhost/TryWebSite/TextFile.txt";
    forceDownloadRemoteFile(sFileVirtualPath);
}
