mod_rewrite redirect loop when forcing the www. on a domain

  • 772

I'm trying to force the www. on only the production server. I do not want to affect the staging server's domain. Here is my current rule:

# Force www
RewriteCond %{HTTP_HOST} !^www.mydomain.com$ #production
RewriteCond %{HTTP_HOST} !^mydomain.s2.mycompany.com$ #staging
RewriteRule ^(.*)$ http://www.mydomain.com/$1 [R=301]

Basically, if the host isn't www.mydomain AND the host isn't mydomain.s2.... then I want to redirect to www.mydomain.com. With the code above, I'm getting a redirect loop.

Any ideas?

apache-2.2 .htaccess redirect mod-rewrite

    Add the "Last" or [L] flag to the RewriteRule like - [R=301,L]:

    RewriteCond %{HTTP_HOST} !^www.mydomain.com$ #production
RewriteCond %{HTTP_HOST} !^mydomain.s2.mycompany.com$ #staging
RewriteRule ^(.*)$ http://www.mydomain.com/$1 [R=301,L]

    That should stop the loop.

    You can review the docs for RewriteRule directive (and others) here: http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html#rewriterule
