Compression Gzip, Brotli

On web hosting servers at Hukot.net, we support three compression formats, widely used and supported Gzip, Deflate, and also the newer, often more efficient, algorithm Brotli from Google. Compression reduces the data demand for transmitted data from the server and speeds up the loading of web pages.

Example of effective compression usage (.htaccess):

# Rules for proper delivery of compressed CSS and JS files.
<IfModule mod_headers.c>
# Serves Brotli compressed CSS files if they exist and the client accepts gzip.
RewriteCond %{HTTP:Accept-encoding} br
RewriteCond %{REQUEST_FILENAME}\.br -s
RewriteRule ^(.*)\.css $1\.css\.br [QSA]

# Serves gzip compressed CSS files if they exist and the client accepts gzip.
RewriteCond %{HTTP:Accept-encoding} gzip
RewriteCond %{REQUEST_FILENAME}\.gz -s
RewriteRule ^(.*)\.css $1\.css\.gz [QSA]

# Serves Brotli compressed JS files if they exist and the client accepts gzip.
RewriteCond %{HTTP:Accept-encoding} br
RewriteCond %{REQUEST_FILENAME}\.br -s
RewriteRule ^(.*)\.js $1\.js\.br [QSA]

# Serves gzip compressed JS files if they exist and the client accepts gzip.
RewriteCond %{HTTP:Accept-encoding} gzip
RewriteCond %{REQUEST_FILENAME}\.gz -s
RewriteRule ^(.*)\.js $1\.js\.gz [QSA]

# Provides the correct content types and prevents double gzip.
RewriteRule \.css\.gz$ - [T=text/css,E=no-gzip:1]
RewriteRule \.js\.gz$ - [T=text/javascript,E=no-gzip:1]
RewriteRule \.css\.br$ - [T=text/css,E=no-gzip:1]
RewriteRule \.js\.br$ - [T=text/javascript,E=no-gzip:1]

<FilesMatch "(\.js\.gz|\.css\.gz)$">

Header set Content-Encoding gzip
# Forces the proxy to cache gzip and non-gzip files for CSS/JS separately.
Header append Vary Accept-Encoding
</FilesMatch>
<FilesMatch "(\.js\.br|\.css\.br)$">
