I've got the following IHttpModule
and I'm trying to figure out how to execute an action from a controller for a given absolute or relative URL.
public class CustomErrorHandlingModule : IHttpModule
{
#region Implementation of IHttpModule
public void Init(HttpApplication context)
{
context.Error += (sender, e) =>
OnError(new HttpContextWrapper(((HttpApplication)sender).Context));
}
public void Dispose()
{}
public void OnError(HttpContextBase context)
{
// Determine error resource to display, based on HttpStatus code, etc.
// For brevity, i'll hardcode it for this SO question.
const string errorPage = @"/Error/NotFound";
// Now somehow execute the correct controller for that route.
// Return the html response.
}
}
How can this be done?
Something along the lines should do the job:
public void OnError(HttpContextBase context)
{
context.ClearError();
context.Response.StatusCode = 404;
var rd = new RouteData();
rd.Values["controller"] = "error";
rd.Values["action"] = "notfound";
IController controller = new ErrorController();
var rc = new RequestContext(context, rd);
controller.Execute(rc);
}
