Hi,
I need to install and configure a server Nginx with Magento.
Magento can enable multi store, so I need to define the equivalent SetEnv on Nginx.

This is the configuration with Apache conf
SetEnv MAGE_RUN_CODE "base" # put here your website or store code
SetEnv MAGE_RUN_TYPE "website" # put here 'website' or 'store'

or with .htaccess
RewriteCond %{HTTP_HOST} ^(.*)example.com
RewriteRule ^ - [E=MAGE_RUN_CODE:example]

and for Nginx?

thank you for any help...
Luca

I would also like help with this. The Magento documentation on this is totally lacking. Here is a link to the Apache wiki which uses either httpd.include files or .htaccess.

Everything I've tried so far results in the following error:
[emerg]: unknown directive "E=MAGE_RUN_CODE:default"
