Can you enable Failed Request Tracing in IIS and see what is going on there?

Hi,

When I browse http://localhost:8004/elmah.axd it shows the errors that occurred in the application, but it also generates 404 error. How I will stop this 404 error?

The details of error is:

<error errorId="deb078c8-d6a5-497a-b9b3-3787da5015fe" 

  application="/" host="UMR4" 

  type="System.Web.HttpException" message="File does not exist." 

 source="System.Web" detail="System.Web.HttpException (0x80004005): File does not exist.&#xD;&#xA;  

 at System.Web.StaticFileHandler.GetFileInfo(String virtualPathWithPathInfo, String physicalPath, HttpResponse response)&#xD;&#xA;   at  System.Web.StaticFileHandler.ProcessRequestInternal(HttpContext context, String overrideVirtualPath)&#xD;&#xA;   at  System.Web.DefaultHttpHandler.BeginProcessRequest(HttpContext context, AsyncCallback callback, Object state)&#xD;&#xA;   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()&#xD;&#xA;   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean&amp; completedSynchronously)" user="2" time="2012-06-13T08:43:04.6200168Z" statusCode="404">

I'm storing error files on a folder named ErrorLogs which is on the root directory of the application.

My webconfig file is like:

............

<configSections>

    <sectionGroup name="elmah">

      <section name="security" requirePermission="false" type="Elmah.SecuritySectionHandler, Elmah"/>

      <section name="errorLog" requirePermission="false" type="Elmah.ErrorLogSectionHandler, Elmah" />

      <section name="errorMail" requirePermission="false" type="Elmah.ErrorMailSectionHandler, Elmah" />

      <section name="errorFilter" requirePermission="false" type="Elmah.ErrorFilterSectionHandler, Elmah"/>

    </sectionGroup>

  </configSections>

<httpHandlers>

      <add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />

</httpHandlers>

<httpModules>

      <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/>

</httpModules>

..........

    <validation validateIntegratedModeConfiguration="false"/>

    <modules>

      <add name="Elmah.ErrorLog" type="Elmah.ErrorLogModule, Elmah" preCondition="managedHandler" />

    </modules>

    <handlers>

      <add name="Elmah" path="elmah.axd" verb="POST,GET,HEAD" type="Elmah.ErrorLogPageFactory, Elmah" preCondition="integratedMode" />

    </handlers>

  <elmah>

    <security allowRemoteAccess="0" />

    <errorLog type="Elmah.XmlFileErrorLog, Elmah" logPath="~/ErrorLogs" />

  </elmah>

I'm running the application on development server. Do I need to host my application on IIS and then I enable Failed Request Tracing?

[James_2JS]

Sorry... are you running "Cassini" from Visual Studio?

[Towhid]

I'm using default development web server that is delivered with VS 2010.

Found the error. Almost all modern browser request for favicon.ico. That's why it was generating 404 error.
