[Authorize] Operation

is there in Service Stack any [Authorize] attribute like in ASP.NET MVC that protect my operations checking the ASP.NET authentication cookie?

ServiceStack has its own [Authenticate] attribute and AuthProvider model that’s separate from ASP.NET Auth.

You should take a look at http://mvc.servicestack.net to see how it integrates MVC + SS Auth.

Otherwise if you want to ignore SS Auth you can register a Custom Request Filter which lets you inspect the underlying ASP.NET Request with:

HttpRequestBase aspReq = httpReq.OriginalRequest as HttpRequestBase;
