Nginx to load balance application servers

Server NGINX
1

I have a blog system with seperate subdomain and domains and want to use
nginx to load balance application servers.

I want to give total number of servers available for example 5 and want
to
redirect all requests to the same server everytime.

For example

a.blog.com will go to server 1
b.bllog.com => server 2
b.bllog.com/x.html => server 2
xx.com => server 1

and so on.

I am thinking doing this by converting domain name “a.blog.com” to
number
with crc32 and modulo that number to number of servers (5) and
remaining
number wiill deceide which server to send this requests.

I wander how to do this. is it through perl or can it be done with
config
file alone. and how to to it in any way?

i think it may use the url_hash
it is not bnuilt-in
you can down the patch from the nginx’s website
