[RÉGLÉ] HTACCESS redirection 301

[freud]

Bonjour,

J'ai Joomla 3.9.19 et comme je ne maitrise pas l'htaccess je souhaiterais savoir SVP si le code de redirection 301 est déjà présent ou si il doit être activé car certain analyseur SEO disent que le code n'est pas présent (Use 301 redirects to drive traffic to URLS with the same domain and sub domain (www and non-www subdomain).):

Voici mon fichier htaccess:

# The line just below this section: 'Options +FollowSymLinks' may cause problems
# with some server configurations.  It is required for use of mod_rewrite, but may already
# be set by your server administrator in a way that dissallows changing it in
# your .htaccess file.  If using it causes your server to error out, comment it out (add # to
# beginning of line), reload your site in your browser and test your sef url's.  If they work,
# it has been set by your server administrator and you do not need it set here.

## Can be commented out if causes errors, see notes above.
Options +FollowSymLinks

## Mod_rewrite in use.

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www.domaine.com [NC]
RewriteRule (.*) http://www.domaine.com/$1 [QSA,R=301,L]

## Begin - Rewrite rules to block out some common exploits.
# If you experience problems on your site block out the operations listed below
# This attempts to block the most common type of exploit `attempts` to Joomla!
#
# Block out any script trying to base64_encode data within the URL.
RewriteCond %{QUERY_STRING} base64_encode[^(]*\([^)]*\) [OR]
# Block out any script that includes a <script> tag in URL.
RewriteCond %{QUERY_STRING} (<|%3C)([^s]*s)+cript.*(>|%3E) [NC,OR]
# Block out any script trying to set a PHP GLOBALS variable via URL.
RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]
# Block out any script trying to modify a _REQUEST variable via URL.
RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2})
# Return 403 Forbidden header and show the content of the root homepage
RewriteRule .* index.php [F]
#
## End - Rewrite rules to block out some common exploits.

## Begin - Custom redirects
#
# If you need to redirect some pages, or set a canonical non-www to
# www redirect (or vice versa), place that code here. Ensure those
# redirects use the correct RewriteRule syntax and the [R=301,L] flags.
#
## End - Custom redirects

##
# Uncomment following line if your webserver's URL
# is not directly related to physical file paths.
# Update Your Joomla! Directory (just / for root).
##

# RewriteBase /

## Begin - Joomla! core SEF Section.
#
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
#
# If the requested path and file is not /index.php and the request
# has not already been internally rewritten to the index.php script
RewriteCond %{REQUEST_URI} !^/index\.php
# and the requested path and file doesn't directly match a physical file
RewriteCond %{REQUEST_FILENAME} !-f
# and the requested path and file doesn't directly match a physical folder
RewriteCond %{REQUEST_FILENAME} !-d
# internally rewrite the request to the index.php script
RewriteRule .* index.php [L]



#
## End - Joomla! core SEF Section.

# php -- BEGIN cPanel-generated handler, do not edit
# This domain inherits the “PHP” package.
# php -- END cPanel-generated handler, do not edit

En vous remerciant

Il me semble que ces lignes de redirection sont déjà présentes

RewriteCond %{HTTP_HOST} !^www.domaine.com [NC]
RewriteRule (.*) http://www.domaine.com/$1 [QSA,R=301,L]

es-ce qu'il faut décommenté la ligne ? :

# RewriteBase /

Comme il existe plusieurs variantes de code ca m'embrouille alors j'ai vu dans un post qu'il faut utiliser le code ci-dessous, pourriez-vous SVP me le confirmer ?
Aussi, es-ce que FORCER HTTPS dans la configuration/serveur fait la même chose ? Merci.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
