Re: acl routing/redirect to specific backend system
Thank you for your reply Bapiste. My setup is using HTTPS so I can't use your suggestion. Is there any other solution when using HTTPS? Thanks in advance!

In your example, you're using HTTPS, so everything is encrypted from a HAProxy point of view. cheers On Mon, Jun 25, 2012 at 5:44 PM, Joeri Blokhuis | DongIT joeri.blokh...@dongit.nl wrote: Hi, I need my 'administrators' to reach specific backend systems. I was hoping this can be done using ACL based on the URL or if there is a more simple way I'm open to suggestions. For example: https://domain.com/x/ where x stands for a specific system. So far I only found ways to balance using ACL on an entire backend but not on a specifc system like test-web01 or test-web02. So is this possible and how would you recommend to implement this (without having to create multiple backends). Thanks in advance!

Re: acl routing/redirect to specific backend system
Brane, I need to have encrypted communication between my frontend and backend. Therefore I don't want to offload SSL on the loadbalancer and then create a new SSL package. The measurement to do this is a little to drastic(e.g. consumes to much resources) for what I want. I can workaround the problem in another way, but was just wondering if it is possible with HAproxy and my setup. Cheers. On Tue, Jun 26, 2012 at 2:44 PM, Brane F.

Re: acl routing/redirect to specific backend system
How do you want to do content switching when the traffic is encrypted
nobody can't.
The only thing you can use is SNI or TCP port which are not encrypted
You could dedicate a port per server, leaving the 443 for the global farm.
IE: use-server srv1 if { dst_port eq 444 }
And in your bind section, don't forget to bind port 444 ;)
there is no other option.
(SNI example:

Can't omit port number using server directive...
Hi friends, I'm trying to allow nginx to delegate https properly and one way I see to prevent from having to write a bunch of backends in haproxy is to omit the port number when using the server directive as follows: frontend https bind :81 accept-proxy maxconn 1 reqadd X-Forwarded-Protocol:\ https reqadd X-Forwarded-Port:\ 443 default_backend cluster backend cluster balance roundrobin fullconn 1 cookie HASESSIONID insert option httpchk HEAD /check.txt HTTP/1.0 server web-3 10.16.26.122 cookie 3 check maxconn 1 server web-4 10.16.26.123 cookie 4 check maxconn 1 When doing this I end up with the following error. Do I need to configure this without the server shorthand maybe? What am I missing? [ALERT] 178/004823 (24130) : parsing [/etc/haproxy/haproxy.cfg:60] : server web-3 has neither service port nor check port. Check has been disabled. [ALERT] 178/004823 (24130) : parsing [/etc/haproxy/haproxy.cfg:61] : server web-4 has neither service port nor check port. Check has been disabled. Also, When it says the client port do you guys think its going to use 81 or 443 in this scenario? We are using stunnel4 with proxy protocol.
