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

[eluser]bleu[/eluser]
Can I redirect in my application/errors/error_404.php to my website controller like www.xyz.com/controller404

I want to write the below in my error files

Code:

header("Location: controller404");

Is this proper from a security point of view?



I want this as I want an error form to be provided which can be filled by the user after which an email will be sent to me.

I want different forms for 404,db,general and php errors
