Hello,
I've been going through haproxy in depth recently, but I can't quite
figure out the details with full, min, and maxconn.
First of all, fullconn confuses me, and this example doesn't help
Example :
# The servers will accept between 100 and 1000 concurrent connections each
#
Is the answer here correct?
http://serverfault.com/questions/205093/restarting-haproxy-without-losing-counters
I would love for the counters to be saved across reloads, but I
haven't seen this in my testing (most extensively on 1.4.11).
Thanks,

Hi Sara,
What you've described is basically what haproxy (or any reverse proxy
for that matter) does. Have you tried using it? Did you have any
problems?

A simple route doesn't work in this case, as the packets have to leave
out the correct interface as well, or they will be dropped by the

I have no idea with ip rules impact performance that much for you.
Anyway, since you're dealing with two interfaces, you can explicitly
bind haproxy to each of them and still have a default route on each
interface. The trick is

apache rewrite rule:

Why are you using a rewrite instead of mod_proxy?
ProxyPass does some nice things by default, like adding the
X-Forwarded-For header
Just throwing my $.02; how about converting the documentation to
something more easily parse-able, like markdown?

This is more for my own curiosity (I'm not advocating a change in the
haproxy defaults) -
Is there any inherit drawback to always using leasconn instead of
roundrobin? Since it uses roundrobin internally when servers are
equally loaded, it seems that this would be the most fair algorithm in
most

Sometimes it's really troublesome not being able to do that, even more
so if a different party administrates the servers.
I'm not sure if you're serious or not, but If
if there's a compelling performance
case, probably because of a shorter data pipeline, but SSL is the cpu
here, not the extra memory copies or buffering (we'll just have to
wait for some tests ;).
Some IT contracts suck. ;)
Yes, they do :)
