Directory Structure

• •

RaQ 3 home page

– /home/sites/home/web –

E.g. a file saved as:

• /home/sites/home/web/testdir/test.html

–

Can be accessed as:

• http:///testdir/test.html

Virtual Site Home Page

– /home/sites//web –

E.g. www.cobalt.com would have a document root of

• /home/sites/www.cobalt.com/web –

Only the RaQ admin and site admin can upload to this directory

CGI Usage

• •
