OWIN OpenIdConnect Middleware - Dynamically Defines RedirectUri

Question

Is there a way to set the RedirectUri property for OpenIdConnectMessage based on the request area, not the application area?

My application serves several domains (myapp.com, myapp.fr, ..) and, based on the domain, determines the default language for the content. I need the user to be returned to the same domain after logging in to IdP, so I need to find a way how RedirectUri is set for the request area, not the application area, as is done by setting middleware options in startup.cs.

This can be done using the Notification event RedirectToIdentityProvider . Something like that:

  Notifications = new OpenIdConnectAuthenticationNotifications { RedirectToIdentityProvider = async n => { n.ProtocolMessage.RedirectUri = n.OwinContext.Request.Uri.Host; n.ProtocolMessage.PostLogoutRedirectUri = n.OwinContext.Request.Uri.Host; }, //other notification events... }
