Hi,
I've been playing with the idea of adding support for the proxy module
to add stickysession cookies on behalf of the backend servers. I have
one case on my hands right now where this would be needed, and I can
think of this being of use for others too.
The way this would work is that if the proxy would see a response from a
backend to which no LB cookie was received either from the client or the
backend, a new cookie would be injected to the response. If the cookie
already exists, nothing would be done. The cookie when added would be
based on the balancer and member-name of the current worker
You can already do this with mod_headers. Just add
Header add Set-Cookie "MYCOOKIE=SOMEVALUE.%{BALANCER_WORKER_ROUTE}e; path=/;"
env=BALANCER_ROUTE_CHANGED
to the proxy block that defines your balancer, use
ProxySet stickysession=MYCOOKIE
and define the routes of your BalancerMembers accordingly
No need for additional code IMHO.
