How to redirect to a action method when a file not found

Question

Hi

I have a action method in a controller and call a html file from this action method.

my controller name is Admin and my action method is ShowAdminDashboard.

when I request Admin/ShowAdminDashboard everything is ok, but when I call a html file from this method, for example login.html, the url changes to Admin/login.html and I face with 404 error page.

I understand it looks on ApplicationPath/Admin/login.html but can't find Admin folder and login.html.

I want to redirect to a specific method instead of showing 404 error page in this situation.in addition I want to redirect just for Admin controller.

 I try overriding HandleUnknownAction for Admin controller but it doesn't work.

 

can you help me?

thanks
