Apache: Protect a folder by a password, but one file is for public access
let us assume you want to protect a whole directory by password and but one file must be readable for public access. This can easily be done by a .htaccess file.
For example: Who want to trotect the folder /var/www/html and only the file public.html should be readable without a password.
Define a username (here “agent”) and create a password file (.htuser)
root@debdevt # htpasswd -c -B /var/www/.htuser agent
Allow from all Satisfy anyAuthName "Only for Agents" AuthType Basic AuthUserFile /var/www/.htuser require user agent
Note:The AuthUserFile must contain the absolute path to the .htuser file.
