Hi there,
What I want to achieve is HA and load balancing for a web-farm handling
many thousands of different sites. For a variety of efficiency and
performence reasons I want to have a form of persistance based on the ``Host:''
header of the incoming packets.
In this way during normal usage requests for a particular site would always end
up at the same backend server. Normal usage is here defined as when load is
acceptable and no failures have occured.
Now I understand that LVS makes most of its decisions in kernel space, and
this sort of data based filtering generally is better off living in user space,
but I also know that the standard kernel masquarading does some work of this
type, for example for re-writing ftp command streams.
So basicaly I'm curious to see if anyone thinks that this sort of scheme will
ever work in LVS, or whether I should go off investigate high-performence
userland relays?
Cheers
Shez
