Application Constants (header, footer)

[eluser]x_dde_x[/eluser]
Still trying to figure Codeigniter out... In my previous sites, I've always constructed around not re-writing header and footer information on each view. For example, I would render the page thusly from the index call:

Code:

include('header');
include('PAGE_URL');
include('footer');

And all meta data and css links would be appended, and the page would be constructed.

Does CodeIgniter have a similar mechanism, or do you have to load other views in each individual view file?
