Want to let user to download a HTML file or a GIF file?

Here is an example that was used on High Country website to let user download MP3 files.

Create a Generic Handler, let's call it Download.ashx

<%@ WebHandler Language="C#" Class="Download" %>
 
 using System;
 using System.Web;
 
 public class Download : IHttpHandler {
     
     public void ProcessRequest (HttpContext context) {
       string fname = context.Request.QueryString["audio"]; // This would be the filename without extension 
       if (fname == null) // No query string
       {
         context.Response.ContentType = "text/plain";
         context.Response.Write("Error");
       }
       else
       {
         fname = "audio/" + fname + ".mp3"; // Complete the filename/path
         string filepath = context.Server.MapPath(fname);
         
         if (!System.IO.File.Exists(filepath)) // File not found
         {
           context.Response.ContentType = "text/plain";
           context.Response.Write("404 File Not Found");
         }
         else // Let user download the file
         {
           context.Response.AddHeader("Content-Disposition", "attachment; filename=\"" + System.IO.Path.GetFileName(fname) + "\"");
           context.Response.ContentType = "audio/mpeg";
           context.Response.WriteFile(filepath);
         }
       }
     }
  
     public bool IsReusable { get { return false; } }
 
 } 

Then in the page that contains the link to the mp3, put this link

<a href="Download.ashx?audio=BrightToOmeo/01 Introduction">4.9 MB DOWNLOAD</a>
