I have written an action filter which detects a new session and attempts to redirect the user to a page informing them that this has happened. The only problem is I can not figure out how to make it redirect to a controller/action combo in an action filter. I can instead only figure out how to redirect to a specified url. Is there a direct way to redirect to a controller/action combo in an action filter in mvc2?
Rather than getting a reference to HttpContent and redirecting directly in the ActionFilter you can set the Result of the filter context to be a RedirectToRouteResult. It's a bit cleaner and better for testing.
Like this:
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
if(something)
{
filterContext.Result = new RedirectToRouteResult(
new RouteValueDictionary {{ "Controller", "YourController" },
{ "Action", "YourAction" } });
}
base.OnActionExecuting(filterContext);
}
