Re: Re: How to select a server based on client ip ?

Thanks, Carlo. It works.

But can it be simpler? such as:

frontend http
 bind :80
 mode http
 default_backend pool 


backend pool
 server s01 2.3.4.1:80
 server s02 2.3.4.2:80
 server s03 2.3.4.3:80
 use_server s01 if { src 217.192.7.0/24 }

We have many servers for different developers, the rules may be complex and 
changing.
It is not elegant to define hundreds of backend.

See the src entry under section 7.5.1 of the HAProxy docs.  There's actually 
many examples of this acl you'll find throughout the doc.  You'd use something 
like this:


frontend http
  bind :80
  mode http
  acl always_s01 src 217.192.7.0/24
  use_backend s01 if always_s01
  default_backend pool 


backend s01
  server s01 2.3.4.1:80 


backend pool
  server s01 2.3.4.1:80
  server s02 2.3.4.2:80
  server s03 2.3.4.3:80

Hi,

If we have 5 servers within a back-end, how can we specify some request to 
certain server based on client ip?

For example:

backend
       server s01
       server s02
       server s03
       server s04
       server s05

How can we make all requests comes from 217.192.7.* goes to server s01 ?

Thanks.
