Question

If I have a <customErrors> section in my Web.config that says to redirect to Error.html, then putting code in the Application_Error method in the Global.asax to redirect to Error.html is redundant is it not? Technically, I could bypass the Web.config by redirecting to a different page in the Application_Error method if I wanted to, but since I don’t want to go to a separate page I don’t think I need the code.

Per this article:

If you have the customErrors redirect in your web.config, you don’t need to do a redirect in the Global.asax‘s Application_Error event. You are right, this would be redundant.

However, I would test it just to be sure. I’ve always just used the Global.asax and redirected from there. I’ve never used the customErrors error page feature.
