Redirect error pages to controller with error form to be filled by user

You want the current url that triggered the 404 to be the current url when sending the 404 header to the browser when throwing the 404 error. If you redirect, it won't be. "controller404" would always be the 404 error, which would be wrong. This is very important for a properly working site and search engines.[/quote]

Then Can I redesign the error pages which are available in errors folder?
