After settings runAllManagedModulesForAllRequests for a ASP.NET web app all WebForms that have their URLs rewritten with Helicon URL rewrite no longer receive their parameters via postback calls.
It looks like these parameters are still available in Application_AuthenticateRequest Global.asax handler, but they are gone right after URL rewrite happens.
Any hints on how to solve this problem without undoing runAllManagedModulesForAllRequests setting?
