Redirect messages

[squishi]

How does the vbulletin redirect work?

Let's say I have this in a plugin's php code:

PHP Code:

if ($_POST['sent'] == '1') {
 $vbulletin->url = '/index.php' . $vbulletin->session->vars['sessionurl'];
 eval(print_standard_redirect('redirect_postthanks_nopermission', true, true));
} 


How do I change the redirect message?
I want to change the "redirect_postthanks_nopermission".
It's not a phrase, nor is it a template, though.

I want the end result to be:

PHP Code:

if ($_POST['sent'] == '1') {
 $vbulletin->url = '/index.php' . $vbulletin->session->vars['sessionurl'];
 eval(print_standard_redirect('redirect_myownredirect', true, true));
} 


with the redirect printing a my own adjusted redirect message.
I don't want to do this for all the redirects on the forum, only for the redirect of this plugin.
