HttpModule for UrlRewriting: Does not work on IIS 6, but
works on ASP Dev Web Server

Hi,

I tried to program my first HttpModule for URL rewriting according to Scotts
Video  "How Do I: Implement URL Rewriting?" on
http://asp.net/learn/videos/video-154.aspx

On my development machine with Visual Studio 2008 and the ASP Deveopment Web
Server, the URL Rewriting works perfect.But as soon as I deploy it on my
production server with Windows 2003 Server and IIS 6, the rewritten URLs lead to
a HTTP 404 error. It seems that the rewriting doesn't work and the events don't
get fired.

Here is my code, for this experiment I try to rewrite/redirect every request to
the Default.aspx page:

1    public class UrlRewriting : IHttpModule
2    {
3    private const int StelleBefehl = 1;
4    5    void context_BeginRequest(object sender, EventArgs e)
6            {
7    // Vorbereitungen8                HttpApplication app =
(HttpApplication)sender;
9    
10               app.Context.RewritePath( "/Default.aspx",
"", "");
11           }
12   13   14   public void Dispose()
15           
17   18   19   public void Init(HttpApplication context)
20           {
21               context.BeginRequest += new
EventHandler(context_BeginRequest);
22           }
23   }
  

I did not forget to register the module in web.config

 

1        <httpModules>
2          <add name="UrlRewriting" type="MyLib.UrlRewriting,
MyLib"/>
3        </httpModules>


Is there any fundamental to think of what I did wrong? How would you check and
find the error? 



Thanks in advance,

Hannes

(HttpApplication)sender;
9 
10 app.Context.RewritePath( "/Default.aspx", "",
"");

Hi Hannes,

This line works:

app.Context.RewritePath( "Default.aspx", "", "");

This is because the virtual path is not allowed to map to another application.

Hi Zhao,

 thank you for your awnser. I have corrected the error you mentioned. But I
think there must be another error, because I did not sucessfully rewrite my
urls.

 
For a test, I thow an exception right after the line 

 

void context_BeginRequest(object sender, EventArgs e)
{
	throw new Exception( "I am in BeginRequest" ); 
}



So the IIS is jumping into this method when I navigate to my Default.aspx page:

http://1.2.3.4/Default.aspx

So far so good. But as soon as I request a URL that should be rewritten, e.g. 

http://1.2.3.4/RewriteThis 

the method "context_BeginRequest" is NOT being called, instead I get
my HTTP 404 error.

 Any suggestions? 

Regards,

Hannes.
