htaccess使用子域重定向

Question

I have a domain example.com and in .htaccess, I am forwarding non-www to www address using below code.

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

Now I created a subdomain test.example.com and because of above rule, its going to http://www.test.example.com , so I thought to write it's own htaccess file to redirect www to non-www. So in the subdomain root, I have .htaccess file with below rule.

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

It's not working and going in a redirect loop , how do I fix it?

Answer 1

Take out the ! and the escapes

RewriteEngine On
RewriteCond %{HTTP_HOST} ^test.example.com$
RewriteRule ^(.*)$ http://test.example.com/$1 [R=301,L]

Answer 2

You don't need 2 rules. Just keep this rule in main .htaccess for your main domain:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [NE,R=301,L]

Now RewriteCond %{HTTP_HOST} ^example\\.com$ condition will only impact main domain leaving your sub domain untouched.

Answer 3

I found a very easy solution for this problem.

My main site document root was /home/example/public_html and subdomain document root was /home/example/public_html/test .

I just changed the document root of subdomain to /home/example/test and it worked.
