Answer 1

You could first download the file from the remote location on your server using WebClient.DownloadFile:

using (var client = new WebClient())
{
    client.DownloadFile("http://remotedomain.com/somefile.pdf", "somefile.pdf");
    Response.WriteFile("somefile.pdf");
}

or if you don't want to save the file temporary to the disk you could use the DownloadData method and then stream the buffer into the response.

UPDATE:

Example with the second method:

using (var client = new WebClient())
{
    var buffer = client.DownloadData("http://remotedomain.com/somefile.pdf");
    Response.ContentType = "application/pdf";
    Response.AppendHeader("Content-Disposition", "attachment;filename=somefile.pdf");
    Response.Clear();
    Response.OutputStream.Write(buffer, 0, buffer.Length);
    Response.Flush();
}
