[AusNOG] Web Application Load Balancer recommendations

[Darren Moss]

Thanks everyone, much appreciated.

We are setting up 2 tests:
1. Squid Proxy (we run that in the office already)
2. HAProxy (the techs seem to like this)

Great responses, thanks again for the input.

Cheers.

Just be wary of piping every single request through some php lookup
script which talks to mysql. That's asking for scaling issues without a
-lot- of thought.
