Hi,
I am able to successfully read the cookie with the following:
RewriteEngine On
RewriteCond %{HTTP_COOKIE} region=us
However, I am not sure how to redirect the traffic to the
balancer://balancer_nodes proxy configuration. It wants to keep the
traffic local which obviously fails. I have tried:
RewriteRule ^/index.html "balancer://balancer_nodes/US/en_US/
stickysession=ROUTEID" [P]
RewriteRule ^/index.html balancer://balancer_nodes/US/en_US/ [P]
RewriteRule ^/index.html /US/en_US/
Thanks,
HB
