In my sites hosted on Dreamhost, the .well-known directory contains an acme-challenge folder along with an .htaccess like this:
# Permit access to the challenge files but nothing else
Order allow,deny
Allow from all
RewriteCond %{REQUEST_URI} ^/[.]well-known/acme-challenge/[a-zA-Z0-9_-]+$
RewriteRule .* - [L]
RewriteRule .* - [F]
Therefore when I put my apple-app-site-association file into .well-known, it isn't seen. How would I modify the .htaccess to permit this? Would I just stick in another line such as
RewriteCond %{REQUEST_URI} /.well-known/apple-app-site-association
?? I don't want to break anything and I know virtually nothing of the syntax in these files, so I'm being rather hesitant.
Change your first rule like this with an OR condition:
RewriteCond %{REQUEST_URI} ^/\.well-known/acme-challenge/[\w-]+/?$ [OR,NC]
RewriteCond %{REQUEST_URI} ^/\.well-known/apple-app-site-association/?$ [NC]
RewriteRule ^ - [L]
Or it can be combined in a single condition also:
RewriteCond %{REQUEST_URI} ^/\.well-known/(?:acme-challenge/[\w-]+|apple-app-site-association)/?$ [NC]
RewriteRule ^ - [L]
