[wp-hackers] wp_head()

[Haluk Karamete]

Hi,

Before the header.php runs wp_head(), information such as the current
page's title can be outputted... How is this possible? I thought, wp
kicks in with the wp_head()!

Also, what file or function figures out whether the current page is a
single, category, tag, 404 etc.. Is that done before the ball is
passed to the theme? or is it done at .htaccss/web.config time?

Thx.
