Sir,

below is the setting in my web.config

<system.webServer>
		<security>
			<requestFiltering allowDoubleEscaping="true">
			</requestFiltering>
		</security>
		<modules runAllManagedModulesForAllRequests="true">

			<add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule,                     System.Web.Routing, Version=4.0.0.0,                     Culture=neutral,                     PublicKeyToken=31BF3856AD364E35" />
			

		</modules>
		<handlers>
            <add name="isapi 4.0" path="*" verb="*" modules="IsapiModule" scriptProcessor="C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" resourceType="Unspecified" requireAccess="None" preCondition="integratedMode,runtimeVersionv4.0,bitness32" />
