An example in aspx (c#)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net;
using System.IO;

public partial class download_file_from_url : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        string url = "http://4rapiddev.com/wp-includes/images/logo.jpg";
        string file_name = Server.MapPath(".") + "\\logo.jpg";

        save_file_from_url(file_name, url);

        Response.Write("The file has been saved at: " + file_name);
    }

    public void save_file_from_url(string file_name, string url)
    {
        byte[] content;
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        WebResponse response = request.GetResponse();

        Stream stream = response.GetResponseStream();

        using (BinaryReader br = new BinaryReader(stream))
        {
            content = br.ReadBytes(500000);
            br.Close();
        }
        response.Close();

        FileStream fs = new FileStream(file_name, FileMode.Create);
        BinaryWriter bw = new BinaryWriter(fs);
        try
        {
            bw.Write(content);
        }
        finally
        {
            fs.Close();
            bw.Close();
        }
    }
}
