+Summary: Streaming an image from an OnBeginRequest handler
+
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+
+
+Steps to reproduce the problem:
+1. Save attached code as 'MonoTestImageStream.cs' and then compile with 
+the following command:
+    mcs /t:library /out:MonoTestImageStream.dll -r:System.Web -
+r:System.Drawing MonoTestImageStream.cs
+
+2. Add the following to Web.config within system.web
+   <httpModules>
+       <add name="MonoTestImageStream" 
+type="MonoTest.MonoTestImageStream, MonoTestImageStream" />
+   </httpModules>
+
+3. Create a blank index.aspx file (possible another bug... under MS.NET a 
+the file doesn't have to exist for this to work.)
+
+4. Goto http://localhost:8080/index.aspx
+
+using System;
+using System.IO;
+using System.Web;
+using System.Drawing;
+using System.Drawing.Imaging;
+
+namespace MonoTest
+{
+        public class MonoTestImageStream : IHttpModule
+        {
+                public void Dispose()
+                {
+                }
+
+                public void Init(HttpApplication app)
+                {
+                        app.BeginRequest += new EventHandler
+(this.OnBeginRequest);
+                }
+
+                public void OnBeginRequest(object s, EventArgs e)
+                {
+                        HttpApplication webApp = (HttpApplication)s;
+
+                        webApp.Context.Response.BufferOutput = true;
+                        webApp.Context.Response.Clear();
+                        webApp.Context.Response.ClearHeaders();
+                        webApp.Context.Response.ClearContent();
+                        webApp.Context.Response.StatusCode = 200;
+                        webApp.Context.Response.ContentType = "image/gif";
+
+                        Bitmap objBitMap = new Bitmap(640, 480);
+                        Graphics g = Graphics.FromImage(objBitMap);
+
+                        g.Clear(Color.Black);
+                        MemoryStream memStream = new MemoryStream();
+
+                        objBitMap.Save(memStream, ImageFormat.Gif);
+                        Byte[] abyte = memStream.ToArray();
+                        memStream.Close();
+                        webApp.Context.Response.OutputStream.Write(abyte, 
+0, abyte.Length);
+
+
+                        webApp.Context.Response.End();
+                        objBitMap.Dispose();
+                }
+        }
+}
+
+
+Actual Results:
+Server hangs
+
+Expected Results:
+Black 640x480 image
+
+How often does this happen?
