+Summary: http module error
+
+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.
+compile this module"
+
+using System;
+using System.Web;
+
+namespace MyModules
+{
+	public class AuthModule : IHttpModule
+	{
+
+		public delegate void MyHandler(object s, EventArgs e);
+		private MyHandler _eventHandler = null;
+
+		public void Init(HttpApplication myApp)
+		{
+			myApp.AuthenticateRequest += new EventHandler
+(OnEnter);
+			myApp.EndRequest += new EventHandler(OnLeave);
+		}
+
+		public void Dispose()
+		{
+		}
+
+		public event MyHandler MyEvent
+		{
+			add { _eventHandler += value; }
+			remove { _eventHandler -= value; }
+		}		
+		
+		public void OnEnter(object s, EventArgs e) 
+		{
+			HttpApplication objApp;
+			HttpContext objContext;
+			string strPath;
+			objApp = (HttpApplication) s;
+			objContext = objApp.Context;
+			strPath = objContext.Request.Path.ToLower();
+
+			if (strPath.Substring(strPath.Length - 10, 10 ) !
+=  "index.aspx") 
+			{
+				if (objContext.Request.Params["username"] 
+== null) 
+				{
+					objContext.Response.Redirect
+("index.aspx");
+				}
+			}
+		}
+
+		public void OnLeave(object s, EventArgs e)
+		{
+		}
+
+	}
+}
+ 
+2. 
+
+Add this to Web.Config file:
+
+    <httpModules>
+      <add name="AuthModule" 
+      type="MyModules.AuthModule,AuthModule" />
+    </httpModules>
+
+3. 
+If you go to index.aspx everything works fine.  I even put some debug code 
+in to verify it made it thru the module.  If I try to go to any other page 
+it crashes.
+
+Actual Results:
+Error
+Description: Error processing request. 
+Error Message:

+Stack Trace: System.NullReferenceException: A null value was found where 
+an object instance was requiredin (unmanaged) 06

+<0x00052> 00 .StateMachine:ExecuteState (IStateHandler,bool&)
+ 
+
+
+
+Expected Results:
+On MS IIS 5.0 with module created with VS.NET, the identical module, and 
+addition to Web.Config works fine.  If you try to go to any page other 
+than index.aspx without having the ?username=xxx in the path then it 
+redirects to index.aspx.
+
+How often does this happen?
