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.

You have either to store your sessions on a common shared  
backend (moderns web scripting languages allows storing  
sessions in memcached or database, but you can also use NFS  
for instance, ..), or just reduce the odd to loose the  
sessions (for instance by using the ip\_hash option for the  
upstream backend, so clients will stick to the same server  
unless nginx detects this servers isn’t available anymore).
