Hello there,
I'm trying to write a mod_proxy_balancer config to implemented
sticky sessions between multiple backend tomcat instances with
stickyness provided by an HTTP header.
eg 1st incoming request is processed by app and responds by
setting a custom HTTP header with a value set at randon. All
subsequent requests are processed by the same back end server.
So I'm trying to figure out a mod_proxy_balancer config which
would support this, or which in general would support sticky
sessions via a custom header that the application has set to a
value.
Need apache proxy rules to forward incoming requests accompanied
by an HTTP header to be sticky to one instance of the tomcat
cluster.
ProxyPass /test balancer://test_cluster/test-app
stickysession=%{
HTTP:X-Test-Header}
<Proxy balancer://test_cluster>

http://giggle:8083 route= ???
BalancerMember
http://giggle:8084 route= ???
</Proxy>
I'm sure I also need to use Header add Set-Cookie and
BALANCER_SESSION_STICK and route set correctly within the config
and perhaps a rewrite rule.
