Below is the configuration, what I need is for all urls like
http//domain.tdl/ww/...
to use back end 1 or 2 or default load balancer,
and all other request to go to Apache, but I get an error:
[ALERT] 170/013846 (5151) : parsing [/etc/haproxy/haproxy.cfg:43] :
error detected while parsing switching rule.
at:
use_backend bck1 if srv1_up srv1 and if has_ww_uri
use_backend bck2 if srv2_up srv2 and if has_ww_uri
is there something I did wrong in my use of "and"?
I will use my IP address in place of 0.0.0.0
I also want to redirect www to root,
and have a status page,
thanks for any help.
