Redirect with .htaccess

The .htaccess file allows you to configure redirects (301 or 302) at the site level without modifying your application code. It is located in the root directory of your site (usually /public_html or equivalent). If the file does not exist, create it (note that the name starts with a dot).

All rules require the mod_rewrite module to be enabled:

RewriteEngine On

Redirect from HTTP to HTTPS

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Alternative variant (when the server uses the X-HTTPS header):

RewriteEngine On
RewriteCond %{HTTP:X-HTTPS} !1
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

Redirect from HTTPS to HTTP

RewriteEngine on
RewriteCond %{HTTPS} on
RewriteRule ^.*$ http://%{SERVER_NAME}%{REQUEST_URI}

Redirect from one page to another

Redirect 301 /test-1/ http://site.ru/test-2/

Alternative using Rewrite:

RewriteCond %{REQUEST_URI} ^/test/$
RewriteRule ^.*$ http://site.ru/new-test/? [R=301,L]

Redirect from www to non-www (main mirror is non-www domain)

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

Redirect from non-www to www (main mirror is www domain)

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

Redirect from trailing slash to no trailing slash (site-wide)

RewriteCond %{REQUEST_URI} !\?
RewriteCond %{REQUEST_URI} !\&amp
RewriteCond %{REQUEST_URI} !\=
RewriteCond %{REQUEST_URI} !\.
RewriteCond %{REQUEST_URI} ![^\/]$
RewriteRule ^(.*)\/$ /$1 [R=301,L]

Redirect from no trailing slash to trailing slash

RewriteCond %{REQUEST_URI} !\?
RewriteCond %{REQUEST_URI} !\&amp

Redirect only site.ru/index.php (no GET parameters) to main mirror site.ru

RewriteCond %{REQUEST_URI} /index.php
RewriteCond %{QUERY_STRING} ^\z
RewriteRule ^(.*)$ http://site.ru/? [R=301,L]

Remove index.php from URLs while preserving GET parameters

Example: site.ru/index.php?n=1 to site.ru/?n=1

RewriteCond %{REQUEST_URI} /index.php
RewriteRule ^(.*)$ http://site.ru/ [R=301,L]

Mass redirect for index.php, index.html, index.htm (e.g. Joomla)

RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.(php|html|htm)\ HTTP/ 
RewriteRule ^(.*)index\.(php|html|htm)$ http://site.ru/$1 [R=301,L]

Redirect dynamic URL with GET parameter to static page

Simple variant:

RewriteCond %{QUERY_STRING} ^id=229
RewriteRule ^.*$ /supermodel/? [R=301,L]

With page:

RewriteCond %{REQUEST_URI} /test/
RewriteCond %{QUERY_STRING} ^id=229
RewriteRule ^.*$ /supermodel/? [R=301,L]

Redirect all pages from one domain to the main page of another domain

RewriteCond %{REQUEST_URI} (.*)
RewriteRule ^(.*)$ http://site.ru/ [L,R=301]

Redirect entire site structure to a new domain (pages to same paths)

RewriteCond %{REQUEST_URI} (.*)
RewriteRule ^(.*)$ http://site.ru/$1 [L,R=301]
