+
+## DO NOT FORGET BEFORE USING: 
+
+* Make sure your FormsAuthentication cookie is set correctly 
+* Verify/change the assembly metadata for System.Web.Extensions which is used to get the Type definition for RestHandlerWithSession:
+```csharp
+Type _RestHandlerWithSessionType = Type.GetType("System.Web.Script.Services.RestHandlerWithSession, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35");
+
+// the "Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" part must match YOUR spesific scenario
+```
