Url Forwarding for invalid routes?

[cruelbarb]

I'm upgrading an old asp.net webforms site. I want to make the URLs look nicer, so I'm using the routing system, like this:\[code\]void RegisterRoutes(RouteCollection routes){ routes.MapPageRoute("account settings", "settings/account/", "~/accountsettings.aspx");}\[/code\]This works fine. Urls like \[code\]mydomain.com/settings/account/\[/code\] look much nicer. However, the page can still be accessed using its physical location, as \[code\]mydomain.com/accountsettings.aspx\[/code\]. I'd like to forward requests to these old form urls to my new urls.What's the best way to do this? Is there a simple method I can use, as with \[code\]RegisterRoutes\[/code\]?
