I am writing an Http module to find the time taken in authentication I have registered for  application.AuthenticateRequest  and application.PostAuthenticateRequest but some post suggest htat authentication is already completed when request hits http module in 6.0 abdt 7.0 classic mode.

I want to know is it true for all authentication types(Basic, integrated, Digest.. etc) and all modes (classic and integrated) i.e for which all combinations I can get correct authenticaton time?
