Konfiguracja oraz uruchomienie mod_brotli

brotli to szybka i dość lekka kompresja będąca bardziej sprawą w stosunku do GZIPa.

Przygotowanie plików w drzewie katalogów

cd /var/www/htdocs/virtuals/__VIRTUAL_HOST__/data

for x in `find ./ -type f -name '*.css'`; do bro --force --input $x --output ${x}.br ; done
for x in `find ./ -type f -name '*.css'`; do gzip -c $x > ${x}.gz ; done
for x in `find ./ -type f -name '*.js'`; do bro --force --input $x --output ${x}.br ; done
for x in `find ./ -type f -name '*.js'`; do gzip -c $x > ${x}.gz ; done
for x in `find ./ -type f -name '*.html'`; do bro --force --input $x --output ${x}.br ; done
for x in `find ./ -type f -name '*.html'`; do gzip -c $x > ${x}.gz ; done
