404.php redirect

[Peter1955]

Hello

Long time reader, first time posting

I want to edit my 404.php file so that it redirects to my own designed 404 page 

I am using a thinkup theme for my site

<?php
/**
 * The template for displaying 404 pages (Not Found).
 *
 * @package ThinkUpThemes
 */

get_header(); ?>

			<?php thinkup_input_404content(); ?>

<?php get_footer(); ?>

and i was told to insert this line

<?php header("Location: http://www.redirect.tomy.url.com/"); ?>

So do i just replace the <?php thinkup_input......  line with the above line edited with the right url??

Any assistance will be very useful as I am not used to php coding as yet

thanks

Is your custom 404 page on some other site?

No it will be on my site. I just have to edit the url when i upload it

Don't use a redirect. Half of the point of a 404 page is that it returns a 404, and using a redirect makes it do something different.

Why not just change the 404.php to be this new page? Wouldn't that be easier?
