: Redirect with HTTP_HOST redirects to sub subdomain The settings I have the following .htaccess rule RewriteCond %{HTTP_HOST} !^www. RewriteCond %{HTTP_HOST} !^de. RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/

@Cugini213

To redirect using the sub-domain as a parameter:


# HTTP 301 Redirect test.*.net -> *.net RewriteCond %{HTTP_HOST} ^test.([^.]+).net$ [NC]
RewriteRule (.*) www.%1.net/ [R=301,L)

# HTTP 301 Redirect test.*.com -> *.com RewriteCond %{HTTP_HOST} ^test.([^.]+).com$ [NC]
RewriteRule (.*) www.%1.com/ [R=301,L)


If you also want to redirect when there's no subdomain (e.g. example.com) to the main website using the subdomain (http://www.example.com):


# HTTP 301 Redirect *.net -> *.net RewriteCond %{HTTP_HOST} ^([^.]+).net$ [NC]
RewriteRule (.*) www.%1.net/ [R=301,L)

# HTTP 301 Redirect *.net -> *.net RewriteCond %{HTTP_HOST} ^([^.]+).com$ [NC]
RewriteRule (.*) www.%1.com/ [R=301,L)


If you're trying to achieve a lot with your .htaccess files you may find it helps to test your conditions and how they affect URL rewriting on the htaccess Made-With-Love website.

In case this is where you struggled, it is always worth remembering that in .htaccess, parameters prefixed with percent symbols (e.g. %1) reference values from the last matched RewriteCond expression, normally values that have been marked as being of interest by being surrounded in brackets (), and parameters prefixed with dollar symbols (e.g. ) reference values in the RewriteRule expression, normally values that are automatically assigned by Apache and relating to the URL.
