Hi Michael,
Seems like you keep wanting to use the hdr(host), can i ask why?
You seem to explain you just want to stick 'src' to a 'server'.. So why
configure hdr(host) ?
Can you try this config? (ps 60 seconds isnt verry long..)
listen http
balance roundrobin
stick-table type ip size 1000000 expire 60s
stick on src
server www01 127.0.0.1 check observe layer7
server www02 127.0.0.2 check observe layer7
server www03 127.0.0.3 check observe layer7

Is there a way to limit the number of sticky connections to a single
server?
I would like to have all traffic to a given virtual host tend to end
up on the same backend server, but also allow the traffic to spread to
multiple servers if more than say 50 connections are already stuck to
a given server. I do need sessions from individual ips to stay stuck,
just new sessions from new ips to stick to a different host. I've
considered a few options, but none of them seem to work.
The first option I tried was:
hash-type consistent
listen http
balance hdr(host)
stick-table type ip size 1000000 expire 60s
stick on src
server www01 127.0.0.1 check observe layer7
server www02 127.0.0.2 check observe layer7
server www03 127.0.0.3 check observe layer7
The problem with this is that all requests for 'host' seem to always
route to the same backend node unless it fails out entirely and then
it all moves to another single node. Perhaps that shouldn't surprise
me, but it did.
I then considered this setup:
listen http
balance roundrobin
stick-table type ip size 1000000 expire 60s
stick on hdr(host)
server www01 127.0.0.1 check observe layer7
server www02 127.0.0.2 check observe layer7
server www03 127.0.0.3 check observe layer7
This also doesn't work and seems to result in basically the same thing
as the first.
I've been reading through the docs, and I can't seem to come up with
any way to do what I am trying to accomplish. I'm guessing that is
because there is not. But I figured I would throw this out to the
list before I scrap my plan and take a different route. Thanks!
