Support of Session affinity in membrane proxy 4.1

[Sachin Garg]

Hi Team,

We are using Membrane Proxy version 4.1 as reverse proxy in our system.

Just now, we got a requirement of managing session affinity in service proxy for multiple nodes.

1) let us know if that is possible.
2) if yes, how we can achieve it.


Regards,
Sachin Garg

Hi Sachin,

1.) Yes

2.)

See:

https://www.membrane-soa.org/service-proxy-doc/3.5/configuration/reference/balancer.htm

Use the jSessionIdExtractor or the xmlSessionIdExtractor.

Have a look at the examples/loadbalancer-session-3 sample.

Cheers,
Thomas

Hi Thomas,

Thanks for your reply.

just need to ask some more points on it.

1) if i mention jSessionIdExtractor in balancer, will that be sufficient to have session affinity in between nodes.below is the proxy.xml which i understood to make session affinity works:

<serviceProxy name="ServiceProxy1" port="2001">

                                <balancer name="Balancer1">

                                                <jSessionIdExtractor />

                                                <clusters>

                                                                <cluster name="Cluster1">

                                                                                <node host="localhost" port="8080"/>

                                                                                <node host="ESEKAVDAHP0067" port="8180"/>

                                                                </cluster>

                                                </clusters>

                                                <roundRobinStrategy/>

                                </balancer>

                </serviceProxy>

Yes, if you have a Java Server that uses the JSESSIONID cookie.

I will not be session aware. If you have a different Cookie you can implement the Extractor interface. A generic cookie extractor would be great.
