Http Subdomain To Https Subdomain In Htaccess

HTTP subdomain to HTTPS subdomain in htaccess – How do you redirect only the HTTP subdomain to the HTTPS subdomain in .htaccess? The main site is in WordPress and already redirected to HTTPS with a plugin, but the subdomain is a PHP created site. I have looked and not seen a conclusive solution to this here. google technical seo best use seo-for-beginners

Force domain to HTTPS but set subdomain to HTTP

This would create a redirect loop (if executed at all). In order to redirect from HTTP to HTTPS, you need to first check you are not already on HTTPS (otherwise you will get a redirect loop).


RewriteEngine on
RewriteCond %{HTTP_HOST} ^subdomain\.example\.com$ [NC]
RewriteRule .? https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

These directives would need to go in the document root of your subdomain. Or at the top of your root (WordPress) .htaccess file if the subdomain points to the document root of the main site. The important thing is that the redirect must go before the WordPress front-controller.

This also assumes your SSL cert is installed directly on your application server and not a proxy.

Try the following:

RewriteEngine On
RewriteCond %{HTTPS} !on
RewriteCond %{HTTP_HOST} ^subdomain\.example\.com [NC]
RewriteRule .? https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

This checks that HTTPS does not contain “on” and the subdomain is being requested before redirecting to HTTPS on the same host.

HTTP subdomain to HTTPS subdomain in htaccess – Although if WP is simply redirecting the main domain, then you could do all this in .htaccess and simply remove the condition that checks against HTTP_HOST. Although if you have other subdomains that should not be redirected to HTTPS then alter the CondPattern to match just the subdomain or main domain (and www subdomain). For example:

RewriteCond %{HTTP_HOST} ^((subdomain|www)\.)?example\.com [NC]

To first force HTTPS, you must check the correct environment variable %{HTTPS} off, but your rule above then prepends the www. Since you have a second rule to enforce www., don’t use it in the first rule.

RewriteEngine On
RewriteCond %{HTTPS} off
# First rewrite to HTTPS:
# Don't put www. here. If it is already there it will be included, if not
# the subsequent rule will catch it.
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# Now, rewrite any request to the wrong domain to use www.
# [NC] is a case-insensitive match
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule .* https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]


About proxying HTTP subdomain to HTTPS subdomain in htaccess

When behind some forms of proxying, whereby the client is connecting via HTTPS to a proxy, load balancer, Passenger application, etc., the %{HTTPS} variable may never be on and cause a rewrite loop. This is because your application is actually receiving plain HTTP traffic even though the client and the proxy/load balancer are using HTTPS. In these cases, check the header instead of the variable. This answer shows the appropriate process


Don’t ever use the solution below because when you are using their code that is something like:

RewriteCond %{HTTPS} off
RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule .*{REQUEST_URI} [L,R=301]

The browser goes to:

Then redirects to:

Then redirects to:

This is too much request to the server.

Most of the answers even accepted one has this problem.
