I,
I need do change .htaccess to have this rule:
visitors visiting :
yoursite.com
can't see the tree of the domain,
but visitors accessing by 2 subdomains of this domain
can see the tree of the domain only inside a certain folder
like this:
z.yoursite.com
can access ../folder/img/
and
x.yoursite.com
can access ../img/
thanks for any help
