how to add virtualhosts in nginx?

[Marcelo]

Hello All,

Following the excellent guide posted in cyberciti.biz
(http://www.cyberciti.biz/faq/rhel-fedora-install-configure-nginx-php5/)
I istalled nginx in centos 5.5 successfully, but I fail to configure
VirtualHosts.

I tried different combinations but it does not work.

Could someone please help me?

I just need an example of a working configuration.

I really appreciate it.

Best Regards,
Marcelo .-
