Hi Dave,
I will be giving a workshop entitled 'Configuring your Professional Server'
at the conference on Thursday next so just to answer your questions for
Robert....
> Does this work in Standard Server, or is it only a feature of
Professional?
This only works on the Professional Edition. The Standard Server only allows
for one witango process.
>> You say you need "3 clients.ini files for each plugin" in your example
(where there's three machines involved) - is that one per machine, or do all
three go somewhere on the same machine?
You will only have 3 clients.ini files if you have 3 webservers. If for
example you have 3 machines all running witango servers but only one is
running a webserver then the clients.ini on the webserver does the load
splitting over the 3 witango servers. This presumes there is only one
witango server running on each machine - if there are 2 on each machine the
load will be split over the 6 witango servers. If you wish it is also
possible to direct requests to a specific server.
>I assume this serves only to load balance and does nothing in cases of
failover - if one of the three machines were to
>crash or be switched off then requests to that IP would return an error, or
is that somehow handled?
One of the things we changed in Witango 5 was that if a server did crash or
was shutdown requests would automatically be redirected to another running
server thus increasing overall stability.
If I can be of any further assistance please do not hesitate to contact me.

Subject: Witango-Talk: To Robert Garcia: Follow up on your message regarding
load balancing
> Way back in January, you wrote a very informative explanation on setting
up multiple WiTango servers in a load balancing scenario by putting each
WiTango server's IP address in clients.ini and witango.ini - ("DNS Round
Robin Load Balancing with WiTango"). I'm getting to where I may have to set
something up along the lines of what you explain, and I wonder if you can
spare a moment to answer a couple extra questions:

If it isn't, is there a way to handle that situation as well? If the client
browser receives 3 IP addresses from a DNS lookup, will it automatically try
a different one if the first is not available?
