Question Apache Load Balaning sticky session issue


Few doubts in apache load balancing -

I want to clear my doubts about apache load balancing.

i have configured apache load balancing for two application servers.

1. When we set load balancing for two application servers then for one connection to application server we will get one jsession id assign to the connection for one application server
Is that mean for that connection apache server will only refer to one application server not go to another application server?

2. route parameter will be added at the end of each jsesion id.
If route is not appended at the end of jsessionid is that a issue? and will result in wrong session stickeyness?

My Configuration -

<Location /balancer-manager>
SetHandler balancer-manager
Order deny,allow
deny from all
Allow from 127.0.0.0
</Location>

<VirtualHost server-apache.com>
ProxyRequests on
ProxyStatus on
ProxyPreserveHost On
RewriteEngine On
LogLevel debug
RewriteLog logs/rewrite.log
RewriteLogLevel 3

Header add Set-Cookie: "ROUTEID=.%{BALANCER_WORKER_ROUTE}e; path=/" env=BALANCER_ROUTE_CHANGED

<Proxy balancer://HB_cluster>
BalancerMember http://server1 loadfactor=1 route=hb1
BalancerMember http://server2 loadfactor=2 route=hb2
ProxySet lbmethod=bytraffic
</Proxy>

ProxyPass /balancer-manager !
ProxyPass / balancer://HB_cluster/ stickysession=ROUTEID
ProxyPassReverse / http://server1/
ProxyPassReverse / http://server2/


ServerAdmin admin@localhost
DocumentRoot "c:/Program Files/Apache Software Foundation/Apache2.2/htdocs/"
ServerName server-apache.com
ErrorLog logs/err-server.log
CustomLog logs/access-server.log common
</VirtualHost>

I am stuck please help.
