Cara mengaktifkan GZIP compression di Apache. Agar setiap virtual host Apache mampu mengkompres data dengan metode GZIP (mod_deflate) tambahkan baris berikut ke dalam konfigurasi httpd.conf
Umumnya lokasi file konfigurasi Apache adalah:
- Linux Centos:
/etc/httpd/conf/httpd.conf - Linux Debian/Ubuntu:
/etc/apache2/httpd.conf
Berikut kodenya
<IfModule mod_deflate.c>
SetOutputFilter DEFLATE
SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|bz2|sit|rar|apk|7z|so|iso|app|doc|ppt|xls|wps|dll)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI .(?:pdf|mov|avi|mp3|mp4|rm|mpeg|asf|wmv|wma|3gp|mkv|flv|f4v|webm|mpg|acc)$ no-gzip dont-vary
AddOutputFilterByType DEFLATE text/*
AddOutputFilterByType DEFLATE application/ms* application/vnd* application/postscript application/javascript application/x-javascript
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
</IfModule>
Simpan dan restart Apache.
