override default bburl value

[Dzi13]

Hi,

i have made simple product which I want use to change default $vbulletin->options['bburl'] vaule.

PHP Code:

$vbulletin->options['bburl'] = 'http://' . $_SERVER['HTTP_HOST']; 


Which hook location should I choose ?

--------------- Added [DATE]1266709180[/DATE] at [TIME]1266709180[/TIME] ---------------

Or in which files is defined $vbulletin->options (values from table setting to options array)

--------------- Added [DATE]1266749503[/DATE] at [TIME]1266749503[/TIME] ---------------

done

--------------- Added [DATE]1266757723[/DATE] at [TIME]1266757723[/TIME] ---------------

I have choose init_startup. Now problem is that it changes bburl always. I wan't to change bburl only in vb cms.
Is there any value where I can see which package is used on that page (blog, article or froum)?
