Htaccess

Disable Browser Cache for specific folder

Place the following line into .htaccess:

Header set Cache-Control "no-store" "expr=%{REQUEST_URI}=~/(VendorName1|VendorName2|requirejs-config\.js)/i"

As result url with "VendorName" in path will get Pragma "no-cache" http header, so browser won't cache it. This trick is very useful for magento developers who are working with js components or html templates and want to disable cache for a certain folder only.

Basic Auth with URL exception

Access /dir/subdir/file.txt file without authorization

SetEnvIf Request_URI "dir\/subdir\/file\.txt$" no_auth
AuthType Basic
AuthUserFile /home/user/public_html/.htpasswd
AuthName "Restricted Area"
Require valid-user
Order allow,deny

Define base path as environment variable for further usage

RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
RewriteRule ^(.*) - [E=BASE:%1]
RewriteRule ^(.*)$ %{ENV:BASE}/index.php [L]
