  • Compression GZIP inactive suite MAJ Joomla 2.5.17

    Bonjour,

    J'ai un problème de compression GZIP sur mon site internet.

    Caractéristiques :
    - Hébergement mutu chez OVH
    - Joomla 2.5.17
    - Gantry 4.1.20
    - Admin Tools Core 2.6.0

    En fait il s'avère que la compression GZIP ne fonctionne pas (vu sur le site http://www.whatsmyip.org/http-compression-test/ )

    Avant passage en J 2.5.17 celle-ci fonctionné parfaitement....

    J'ai vérifié le fichier .htaccess, il s'agit bien du bon et il n'a pas été remplacé. ( CHMOD 404 )

    Ci-joint le contenu du fichier :
    Code HTML:

    Avec la compression GZIP j'avais plutôt une bonne moyenne sur GTMETRIX ( B / B ) mais là c'est retombé a du ( D / C ) et il est clairement indiqué comme quoi le conseil pour augmenter la rapidité est d'utiliser la compression GZIP...

    Auriez-vous une piste ?

    Merci d'avance,
    Bien cordialement,

    Re : Compression GZIP inactive suite MAJ Joomla 2.5.17

    Bonjour à tous,

    J'ai fait des test supplémentaires,

    J'ai utilisé cette ligne

    Code HTML:
     #Mode deflate OVH
    
    AddOutputFilterByType DEFLATE text/html text/xml application/xhtml+xml text/plain application/javascript text/css
    à la place de ces lignes là

    Code HTML:
    # Compression MOD_DEFLATE
    
    SetOutputFilter DEFLATE
    AddOutputFilterByType DEFLATE text/html text/css text/plain text/xml application/x-javascript application/x-httpd-php
    #Pour les navigateurs incompatibles
    BrowserMatch ^Mozilla/4 gzip-only-text/html
    BrowserMatch ^Mozilla/4\.0[678] no-gzip
    BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
    BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html
    #ne pas mettre en cache si ces fichiers le sont déjà
    SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip
    #les proxies doivent donner le bon contenu
    Header append Vary User-Agent env=!dont-vary
    
    
    
    # Compression GZIP Mod_GZIP
    
    RewriteEngine on
    ReWriteCond %{HTTP:accept-encoding} gzip
    RewriteCond %{HTTP_USER_AGENT} !Safari
    ReWriteCond %{REQUEST_FILENAME} !^.+\.gz$
    RewriteCond %{REQUEST_FILENAME}.gz -f
    RewriteRule ^(.+) $1.gz [QSA,L]
    <IfModule mod_gzip.c>
    mod_gzip_on Yes
    mod_gzip_dechunk Yes
    mod_gzip_keep_workfiles No
    mod_gzip_can_negotiate Yes
    mod_gzip_add_header_count Yes
    mod_gzip_send_vary Yes
    mod_gzip_command_version '/mod_gzip_status'
    mod_gzip_min_http 1000
    mod_gzip_minimum_file_size 300
    mod_gzip_maximum_file_size 512000
    mod_gzip_maximum_inmem_size 60000
    mod_gzip_handle_methods GET POST
    mod_gzip_temp_dir /tmp
    mod_gzip_item_include file \.html$
    mod_gzip_item_include file \.php$
    mod_gzip_item_include file \.pl$
    mod_gzip_item_include file \.rb$
    mod_gzip_item_include file \.py$
    mod_gzip_item_include file \.cgi$
    mod_gzip_item_include file \.css$

    mod_gzip_item_include mime ^application/x-javascript$
    mod_gzip_item_include mime ^text/.*
    mod_gzip_item_include mime ^httpd/unix-directory$
    mod_gzip_item_include handler ^cgi-script$
    mod_gzip_item_include handler ^server-status$
    mod_gzip_item_include handler ^server-info$
    mod_gzip_item_include handler ^application/x-httpd-php
    mod_gzip_item_exclude mime ^image/.*
    </IfModule>
    Sous Chrome, si je test via http://www.whatsmyip.org/http-compression-test/ le site est compressé par contre sur GTMetrix, le rapport me dit que non.

    Sous Firefox, si je test via http://www.whatsmyip.org/http-compression-test/ le site est compressé uniquement lorsque je fais un second test. Par contre sur GTMetrix, le rapport me dit qu'il n'est pas compressé.

    Dans un second temps, j'ai activé la Compression GZIP via le backend de Joomla -> résultat identique, site compressé d'après http://www.whatsmyip.org/http-compression-test/ mais sur GTMetrix le rapport m'indique qu'il n'y a pas de compression GZIP.

    Une idée ?
    Merci d'avance,
