Issues with Apache redirect to www-prefixed URL

  • 772

I have a website with domain mysite.com. I would like to have it so that if a user types in "mysite.com" it will redirect to "www.mysite.com". Additionally, "mysite.com/subdir" will also redirect to "www.mysite.com/subdir". I've looked and made changes with vhosts and also rewrites, but it's not working for the "mysite.com/subdir"->"www.mysite.com/subdir" case. Every time I type in "mysite.com/subdir", it will redirect to "www.mysite.com". Only "www.mysite.com/subdir" works.

Not sure how to troubleshoot this. I turned on rewrite logs and didn't see anything obvious, yet.

This is my config files so far. Please let me know what I'm missing. Thanks!

FYI: I'm using CentOS 5.4, nginx 1.2.0 on top of Apache 2.2.3. The site itself is built with CodeIgniter framework.

  1. Just have nginx do the redirection instead of passing them up to Apache.

    Example:

    server {
   listen [::]:80;
   server_name example.com vip.example.com;
   return 301 $scheme://www.example.com$request_uri;
}

    (Taken from my site www.yes-www.org)

  2. Your apache RewriteRule will not work; also, do not use .htaccess files if you can avoid doing so.

    The Redirect inside the mysite vhost is sufficient to have all requests end up at www.mysite.com.

    However, the subsequent RewriteRule would rewrite everything to /index.php/$0 (literally), since $0 doesn't mean anything.

    Why is nginx proxying everything to an apache backend ? What, exactly, does nginx add here ?

    You should collect logs from apache (inspect both the access and the error logs) to determine what is happening.
