I need to use haproxy for listening to port 80 and forward the request if it matches the role for that I did this this but I don't know how I can tell to use the prober back end
frontend httpfw
bind *:80
mode http
acl # what I must write here to defend a domain like test1.com
acl # what I must write here to defend a domain like test2.com
use_backend httptest1 if # how can I told to use this backend if the request comes from test1.com
use_backend httptest2 if # how can I told to use this backend if the request come from test2.com
backend httptest1
mode http
balance source
server httptest1 1.1.1.1:80
backend httptest2
mode http
balance source
server httptest2 2.2.2.2:80
Thanks :)
