FastCGI in various servers

[Antonio]

Hello,

I have a question about fastcgi. If I use 5 web server with fastcgi, 
with a script that works with session variables, if it balances the 
request to another different server. How to access the session 
variables? As will be stored in another /tmp/SESSION_XXX (other machine).

I can use in nginx fastcgi servers located on another machine, some 
configuration examples?. Thanks.

Regards,
Anthony.
