Hi all,
I need some help here.

If I'm building a large websitehttp://www.domain.com and I want to install CMS inhttp://www.domain.com/about but the header and footer of the website will be built separately using SSI and incorporated into the other parts of the website which will not use Concrete5.

The directory structure will be something like this:

/
/about (Concrete5 installed here)
/includes/header.html
/includes/footer.html

and inside /includes/header.html, it refers to:
/inc/header-components/header-a.html
/inc/header-components/header-b.html
/inc/header-components/header-c.html

How would I get the header and footer to work in myhttp://www.domain.com/about without duplicating the header and footer includes files into my theme folder. I only want to use the existing header and footer because it will be a huge website and we want to keep the header and footer standardised and accurate all the time.

How would the path be to refer to the files in the root folder (one or more levels up from my C5 theme folder)?

Appreciate your urgent advice.

Thanks!
