[Openuss-developers] Re: [enhydra] Session Replication at Enhydra Director

[Sinisa M. <si...@pr...>]

Hi Lofi,

Enhydra Director can't be used to replicate sessions between Enhydra
instances. If sessionAffinity="false" (parameter of Tomcat connector - in
our case Director Connector), Director will redirect requests based on
round-robin algorithm. In than case, Director will not take care about
sessions. If sessionAffinity=true, requests from the same session will be
redirect to the same application server. But if one server will stop,
requests from sessions which were stored on that server, will be redirected
to the next app. server as a new sessions.


Regards,
Sinisa
