Hello.
We have a setup with two reverse proxies, two frontends and two backend
application servers. Usually we just use LVS to switch between the proxies,
and then establish a direct mapping from each of the reverse proxies onto an
application server. But now I am wondering if it is possible to use LVS to
switch between the two frontends and the two backends as well, in other
words to cluster the frontends and backends. Regular persistence doesn't
work here, because (as far as the backends are concerned) all the traffic
comes from just two addresses. It would be really nice to be able to inspect
the session ID (which is contained in the http header of the requests) and
route the request based on that. But is it possible? Has anybody done this?
Any thoughts?
