  <system.web>

    <!--  DYNAMIC DEBUG COMPILATION
          Set compilation debug="true" to insert debugging symbols (.pdb information)
          into the compiled page. Because this creates a larger file that executes
          more slowly, you should set this value to true only when debugging and to
          false at all other times. For more information, refer to the documentation about
          debugging ASP.NET files.
    -->
    <compilation defaultLanguage="vb" debug="true" />

    <!--  CUSTOM ERROR MESSAGES
          Set customErrors mode="On" or "RemoteOnly" to enable custom error messages,
          "Off" to disable. Add <error> tags for each of the errors you want to handle.
    -->
    <customErrors mode="RemoteOnly" />

    <!--  AUTHENTICATION
          This section sets the authentication policies of the application. Possible modes are
          "Windows", "Forms", "Passport" and "None"
    -->
    <authentication mode="Windows" />


    <!--  AUTHORIZATION
          This section sets the authorization policies of the application. You can allow or
          deny access to application resources by user or role. Wildcards: "*" means
          everyone, "?" means anonymous (unauthenticated) users.
    -->
    <authorization>
        <allow users="*" /> <!-- Allow all users -->

            <!--  <allow     users="[comma separated list of users]"
                             roles="[comma separated list of roles]"/>
                  <deny      users="[comma separated list of users]"
                             roles="[comma separated list of roles]"/>
            -->
    </authorization>

    <!--  APPLICATION-LEVEL TRACE LOGGING
          Application-level tracing enables trace log output for every page within an
          application. Set trace enabled="true" to enable application trace logging.  If
          pageOutput="true", the trace information will be displayed at the bottom of each
          page. Otherwise, you can view the application trace log by browsing the
          "trace.axd" page from your web application root.
    -->
    <trace enabled="false" requestLimit="10" pageOutput="false"
          traceMode="SortByTime" localOnly="true" />


    <!--  SESSION STATE SETTINGS
          By default, ASP.NET uses cookies to identify which requests belong to a particular
          session. If cookies are not available, a session can be tracked by adding a session
          identifier to the URL. To disable cookies, set sessionState cookieless="true".
    -->
    <sessionState
            mode="InProc"
            stateConnectionString="tcpip=127.0.0.1:42424"

            cookieless="false"
            timeout="20"
    />

    <!--  PREVENT SOURCE CODE DOWNLOAD
          This section sets the types of files that will not be downloaded. As well as entering
          an HttpHandler for a file type, you must also associate that file type with the
          xspisapi.dll in the App Mappings property of the Web site, or else the file can be
          downloaded. It is recommended that you use this section to prevent your sources
          from being downloaded.
    -->
