I am trying to allow the access to the elmah.axd 
file for only a perticular login and all others should be denied. I have followed Phil Haack's tutorial  for securing the 
file.   
<httpHandlers>
            <remove verb="*" path="*.asmx"/>
            <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
            <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
            <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false"/>
            <add verb="POST,GET,HEAD" path="admin/elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />
        </httpHandlers>
<location path="admin">
    <system.web>
        <authorization>
            <allow users="
[email protected]"/>
            <deny users="*"/>
        </authorization>
    </system.web>
</location>
First I logged in as 
[email protected] and tried to access the http://localhost:58961/admin/elmah.axd 
file and I am rightly being redirected to the Login.aspx page. Next I logged in as 
[email protected] and was able to access the elmah 
file at http://localhost:58961/admin/elmah.axd. Now I logged in again as 
[email protected] and I was able to access the emlah 
file now. What is the reason for this behavior?
