Need an Apache .htaccess expert. I want to give open access to a directory on my site to all queries coming from an external subdomain:
e.g. [url removed, login to view]
All other comers need to have a login and password.
This basically is modifying appropriately an .htaccess file. Some possibilities have been discussed here: [url removed, login to view]
Please only respond if you are an expert with .htaccess files.
