Hi Chinmaya,
Below is the code for Request Token attribute
public class FliteTokenAttribute : AuthorizeAttribute
{
public override void OnAuthorization(System.Web.Http.Controllers.HttpActionContext actionContext)
{
if (HttpContext.Current.Request.Headers["RequestVerificationToken"] != null)
{
if (AuthorizeRequest(actionContext))
{
return;
}
}
HandleUnauthorizedRequest(actionContext);
}
protected override void HandleUnauthorizedRequest(System.Web.Http.Controllers.HttpActionContext actionContext)
{
base.HandleUnauthorizedRequest(actionContext);
actionContext.Response = new HttpResponseMessage(HttpStatusCode.NotAcceptable);
}
private bool AuthorizeRequest(System.Web.Http.Controllers.HttpActionContext actionContext)
{
try
{
string cookieToken = "";
string formToken = "";
IEnumerable tokenHeaders;
if (actionContext.Request.Headers.TryGetValues("RequestVerificationToken", out tokenHeaders))
{
string[] tokens = tokenHeaders.First().Split(':');
if (tokens.Length == 2)
{
cookieToken = tokens[0].Trim();
formToken = tokens[1].Trim();
}
}
AntiForgery.Validate(cookieToken, formToken);
return true;
}
catch
{
return false;
}
}
}

Action, Authentication, Authorization , Result , Exception these are the base filters .

The best materials about not only Filtering, but also Pagination and Sorting can be found on the Asp.Net official website it self.
