Hi Daniel , Following is the case.
[image: Inline images 1] My Query is : 1: When users are serving the webpages,and my *Apache1 *get down, HaProxy shifted the traffic to *Apache2*. But i don't want to shift this traffic to *Apache2 *when my *Apache1 *is down, cause my application is session base. I want, those are serving from *Apache1 *, they should keep on *Apache1*. not to shift on *Apache2*. I want to apply Force sticky session in Haproxy.
