Re: [GMG-Devel] Fixed the apache config example in the wiki

[Christopher Allan Webber]

New solution!  I'm happy with this one!

<VirtualHost *:80>
  Options +ExecCGI

  # Accept up to 16MB requests
  FcgidMaxRequestLen 16777216

  ServerName mediagoblin.example.org

  Alias /mgoblin_static/ /path/to/mediagoblin/mediagoblin/static/
  Alias /mgoblin_media/ /path/to/mediagoblin/user_dev/media/public/

  ScriptAlias / /path/to/mediagoblin/mg.fcgi/
</VirtualHost>
