haproxy(二)配置session粘连

我使用TOMCAT6.0分别开启了8080和8081端口的应用
前面是haproxy做LOADBALANCE的代理
配置文件如下：

global
log 127.0.0.1 daemon debug
maxconn 4096
pidfile /usr/local/haproxy/logs/haproxy.pid
daemon
defaults
log global
stats uri /stats
stats auth sillycat:kaishi
mode http
option dontlognull
retries 3
option redispatch
maxconn 2000
contimeout 5000
clitimeout 50000
srvtimeout 50000
listen     webhttp 0.0.0.0:80
mode http
option httpchk GET /demo/ping.jsp
cookie DEMOCOOKIE insert nocache
balance roundrobin
server app1 127.0.0.1:8080 cookie app1inst1 check
server app2 127.0.0.1:8081 cookie app2inst2 check

分别在两个TOMCAT上启动两个应用，一个easystatic是些静态页面，一个easylogon，需要cookies登陆访问

global
log 127.0.0.1 daemon debug
maxconn 4096
pidfile /usr/local/haproxy/logs/haproxy.pid
daemon
defaults
log global
stats uri /admin/status
stats auth sillycat:kaishi
mode http
option dontlognull
retries 3
option redispatch
maxconn 2000
contimeout 5000
clitimeout 50000
srvtimeout 50000
