domain.com/subdomain -> subdomain.domain.com (r         


        

Answer 1

This is a wildcard based solution, so it sould work for any number of subdomains.

This will redirect domain.com/foo/bar to foo.domain.com/bar:

RewriteCond %{HTTP_HOST} ^domain.com$ [NC]
RewriteRule ([^/]+)(/.*|$) $1.domain.com/$2 [R=302]

This will handle (internal rewrite) the virtual hosts:

RewriteCond %{HTTP_HOST} ^(.*).domain.com$ [NC]
RewriteRule (.*) %1/$1 [L]

You might consider using 301 (permanent redirect) instead of the 302.

I strongly suggest you have a VirtualHost for your main site domain.com or www.domain.com and a separate one for handling the virtual subdomains.

For only a certain subdomain:

RewriteCond %{HTTP_HOST} ^domain.com$ [NC]
RewriteRule (subdomain)(/.*|$) $1.domain.com/$2 [R=302,L]

RewriteCond %{HTTP_HOST} ^(subdomain).domain.com$ [NC]
RewriteRule (.*) %1/$1 [L]
