How-to enable GZIP compression on Apache2? I have apache-mod_deflate!

SiB · January 25, 2011

Hello, I can see at last point of step 2 of installation process RED text:

GZIP compression is on (recommended)

I install PrestaShop on my own Apache2 system with correct module: apache-mod_deflate-2.2.17-3.i686.
I have in PHPINFO this information:

Loaded Modules core prefork http_core mod_so mod_alias mod_auth_basic mod_authn_file mod_authz_groupfile mod_authz_user mod_env mod_expires mod_headers mod_include mod_negotiation mod_setenvif mod_speling mod_version mod_authz_host mod_log_config mod_mime mod_mime_magic mod_userdir mod_deflate mod_dir mod_php5

Apache Environment \ HTTP_ACCEPT_ENCODING gzip,deflate
HTTP Headers Information \ Accept-Encoding gzip,deflate
PHP Variables \ _SERVER["HTTP_ACCEPT_ENCODING"] gzip,deflate

My config /:

# $Id: apache-mod_deflate.conf,v 1.10 2009/05/26 15:14:24 psz Exp $
LoadModule deflate_module        modules/mod_deflate.so

# Safe but working settings - compress only that types:
AddOutputFilterByType DEFLATE application/javascript application/x-javascript
AddOutputFilterByType DEFLATE application/x-httpd-php
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE image/svg+xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/html 
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/xml

# Compress all and exclude only few things - may cause some problems:
#SetOutputFilter DEFLATE


   # Netscape 4.x has some problems...
   BrowserMatch ^Mozilla/4 gzip-only-text/html

   # Netscape 4.06-4.08 have some more problems
   BrowserMatch ^Mozilla/4\.0[678] no-gzip

   # MSIE masquerades as Netscape, but it is fine
   BrowserMatch \bMSIE !no-gzip !gzip-only-text/html

   SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary
   SetEnvIfNoCase Request_URI \.pdf$ no-gzip dont-vary
   SetEnvIfNoCase Request_URI \.(?:exe|t?gz|zip|bz2|sit|rar|iso)$ no-gzip dont-vary



   # Make sure proxies don't deliver the wrong content
   Header append Vary User-Agent env=!dont-vary

I try replace mid part to this (no effect):

# Compress all and exclude only few things - may cause some problems:

SetOutputFilter DEFLATE

and to this (no effect, too):

# Compress all and exclude only few things - may cause some problems:
SetOutputFilter DEFLATE

Can you have any idea? Thanks for any help.

How can I enable compression to themes/default/cache?
this is what i get from PageSpeed Insights and gtmetrix.com:

Compressing the following resources with gzip could reduce their transfer size by 247.8KiB (73% reduction).

Compressing http://www.tekcenter...894ca5515689.jscould save 152.2KiB (69% reduction).
Compressinghttp://www.tekcenter...b9d80ce_all.css could save 80.7KiB (82% reduction).
Compressing http://www.tekcenter...pluginDetect.js could save 14.9KiB (65% reduction).

My prestashop version is: 1.5.6.2 (Default theme)

my current .htaccess code is this:

SetEnv HTTP_MOD_REWRITE On
