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>
BalancerMember http://giggle:8081 route= ???
BalancerMember http://giggle:8082 route= ???
BalancerMember 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.
So... what exactly is your question ?
Which part of the mod_proxy_balancer documentation is unclear ?
Thanks,
