URL Mapping - ApacheCon 2005
mod_rewrite examples (2)
  • Problem: Want arbitrary user to have a website at "username.example.com"

  • Don't want to have to set up vhosts for everyone

  • Solution: "wild-card" cname in DNS:

    
    *   86400   IN  CNAME  www.example.com.
    		  

  • Then, a rewrite rule:

    
    RewriteEngine on
    RewriteCond %{HTTP_HOST} ^(.+)\.example\.com$
    RewriteRule ^(.+)$ /home/%1/public_html$1
    		  

  • %1 contains the match from the RewriteCond

  • $1 contains the match from the RewriteRule

  • Note that you can also do this with mod_vhost_alias
