Using variable in vhost

[huguesjoyal]

Hi,

I don't see any reason why it can be slower since the recommended ways to
pass params to fastcgi is by using dynamics variables ex: fastcgi_param
SCRIPT_FILENAME $document_root$fastcgi_script_name; 

The way you're setting your variable is static by the website, the value is
not dynamically linked to the request. So it might have a sight overhead
when starting the web server for parsing the config, instead of having the
full config repeated for each virtual host, but overall once the "virtual
server" is loaded into memory it's shouldn't be a problem.

Thanks
