Im trying to understand URL re-writing. In my Global.asax file I have the line:

base.BeginRequest += new EventHandler(Global_BeginRequest);

in the Session_Start method. It hits the line and creates it, but it never hits the event handler? Any ideas why?

Hi,

As far as I know, you should implement the event-handler in a IHttpModule's init method this way:

C#

public void Init(HttpApplication context)
{
    context.BeginRequest += context_BeginRequest;
}

and add the HttpModule class you created in the web.config httpModule- / modules-Section:

<configuration>
    <system.web>
        <httpmodules>
            <clear />
            <add name="RedirectHandler" type="RedirectorModule.RedirectHandler" />
            <add name="RewriteHandler" type="RedirectorModule.RewriteHandler" />
        </httpmodules>
    </system.web>
    <system.webserver>
        <modules runallmanagedmodulesforallrequests="true">
            <remove name="RedirectHandler" />
            <add name="RedirectHandler" type="RedirectorModule.RedirectHandler" />
            <remove name="RewriteHandler" />
            <add name="RewriteHandler" type="RedirectorModule.RewriteHandler" />
        </modules>
    </system.webserver>
</configuration>

For more informations, I made a blog entry about a basic URL Rewriter:

Hope this helps.

Best regards and happy coding,
Stops
