Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)

public void RedirectToRoutePermanent(
	string routeName,
	RouteValueDictionary routeValues
)

Parameters

routeName
Type: System.String

The name of the route.

routeValues
Type: System.Web.Routing.RouteValueDictionary

The route parameter values.

HttpException

Redirection was attempted after the HTTP headers had been sent.

This method is provided for coding convenience. It is equivalent to calling the Redirect(String, Boolean) method with the second parameter set to false.

This method calls the RouteCollection.GetVirtualPath method to determine the URL.

ASP.NET performs the redirection by returning a 301 HTTP status code.

The following example shows how to call this method to redirect to a route that is named Product and that has parameters that are named productid and category.

Response.RedirectToRoutePermanent("Product",
  new RouteValueDictionary {productId="1", category="widgets"});
