I placed thin on my web.config file
<customErrors mode="On" defaultRedirect="~/ErrorPages/Oops.aspx">
<error statusCode="404" redirect="~/ErrorPages/PageNotFound.html" />
</customErrors>
to redirect my custom 404 page not found on the file above. But its not working.
Do I need to add other configurations and code to make this work? Am I missing something? That's the only configuration I did.
