ASP.NET

I am implementing URL rewriting in my project werein i want my URL:
http://localhost:54611/WebSite6/Customer.aspx[^]

to look like:
http://localhost:54611/WebSite6/Customer[^]

I added Intelligencia.UrlRewriter.dll to my bin folder.

And i added the below written code in my web.config file.

<configuration>
  <configSections>
    <section name="rewriter" requirePermission="false" type="Intelligencia.UrlRewriter.Configuration.RewriterConfigurationSectionHandler, Intelligencia.UrlRewriter"/>
  </configSections>
    <connectionStrings>
        <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>
    </connectionStrings>
    <system.web>
    <httpModules>
      <add name="UrlRewriter" type="Intelligencia.UrlRewriter.RewriterHttpModule, Intelligencia.UrlRewriter"/>

    </httpModules>
    <compilation debug="true" targetFramework="4.0"/>
        <authentication mode="Forms">
            <forms loginUrl="~/Account/Login.aspx" timeout="2880"/>
        </authentication>
        <membership>
            <providers>
                <clear/>
                <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/"/>
            </providers>
        </membership>
        <profile>
            <providers>
                <clear/>
                <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/"/>
            </providers>
        </profile>
        <roleManager enabled="false">
            <providers>
                <clear/>
                <add name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" connectionStringName="ApplicationServices" applicationName="/"/>
                <add name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" applicationName="/"/>
            </providers>
        </roleManager>
    </system.web>
    <system.webServer>
    <handlers>
      <remove name="ExtensionlessUrl-Integrated-4.0"/>
    </handlers>
    <modules runAllManagedModulesForAllRequests="true">

      <add name="UrlRewriter" type="Intelligencia.UrlRewriter.RewriterHttpModule"/>
    </modules>
    <validation validateIntegratedModeConfiguration="false"/>
    </system.webServer>

  <rewriter>
    <rewrite url="~/Customer$" to="~/Customer.aspx" ignoreCase="true" />
  </rewriter>
