Multi-tenancy support

[Cecil Wei]

Hi all,

I have been working on a project that we need to support more than 10000
tenants. I tried to create multiple virtual servers and each listen to
different ports and I found that I can only create up to 300 virtual
servers due to the limitation of FD_SETSIZE. In this case I will need to
have more than 300 servers running which doesn't seem to make much sense.

I also consider the option of creating multiple client sections to specify
the source IP addresses and the corresponding virtual server. However, I
don't seem to find a way to identify tenants if the incoming traffic is
from the same proxy server.

I am running out of options and hoping that you may share your experience
or suggestions.

thank you very much
