I have a page structure on my site, where different products is placed in different subdirs, e.g:

/mainmenu/product-a
/mainmenu/product-b
/mainmenu/product-c

And for every subdir there will be a lot of pages and sub-subdirs.

How do the expression i the extra section look, when I want to count the page-hits for each group (e.g. all hits from /mainmenu/product-a
and below)?
