Question

Hi all I know that this has been posted as a prior question several times, but I’ve gone through each question and their proposed solutions and I’m still not able to surmount my 404 issue. I’m running Elmah 1.1 32-bit. I’ve referred to ASP.NET MVC – Elmah not working and returning 404 page for elmah.axd but I haven’t had any luck after applying the suggestions.

I’m running ASP.NET MVC 3. Here’s my web.config:

…

<httpHandlers>
  <add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />
</httpHandlers>
<httpModules>
  <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/>
  <add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah" />
  <add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah" />
</httpModules>

…

<errorLog type="Elmah.SqlErrorLog, Elmah"
    connectionStringName="dbconn" />

    <errorFilter>
        <test>
            <jscript>
                <expression>
                <![CDATA[
                // @assembly mscorlib
                // @assembly System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
                // @import System.IO

                HttpStatusCode == 404
                || BaseException instanceof FileNotFoundException 
                || BaseException instanceof HttpRequestValidationException
                /* Using RegExp below (see http://msdn.microsoft.com/en-us/library/h6e2eb7w.aspx) */
                || Context.Request.UserAgent.match(/crawler/i)                      
                || Context.Request.ServerVariables['REMOTE_ADDR'] == '127.0.0.1' // IPv4 only
                ]]>
                </expression>
            </jscript>
        </test>
    </errorFilter>

I have my .axd routes ignored using:
routes.IgnoreRoute(“{resource}.axd/{*pathInfo}”);

I’m running the site on IIS7, 32 bit mode enabled. I’ve tried many different configuration options but all to no avail. Any ideas?

Thanks
Shan

My bad. My .axd ignore route rule was ordered after the default route mapping. The default route mapping rule was matching the URL elmah.axd. I guess I didn’t realize that the ignore rules had to be listed above this route. Thanks everyone for your help!

    routes.MapRoute(
        "Default", // Route name
        "{controller}/{action}/{id}", // URL with parameters
        new
        {
            controller = "Home",
            action = "Index",
            id = UrlParameter.Optional
        } // Parameter defaults
    );

    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

Simply moving routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); before the Default route mapping resolved this issue.
