RE: reloading haproxy
This is what I use to reload: haproxy -D -f /etc/lb-transparent-slave.cfg -sf $(pidof haproxy) (Which has pidof lookup process id instead of file it in a file, but that shouldn't matter.) The main problem is you are (-st) terminating (aborting) existing connections instead of (-sf) finishing them. -Original Message- From: Adrian Moisey [mailto:adr...@careerjunction.co.za] Sent: Thursday, May 14, 2009 4:33 AM To: haproxy@formilux.org Subject: reloading haproxy Hi I am currently testing HAProxy for deployment in our live environment.

R: Transparent proxy
I've solved my problem (many thansk to John) but now I've another problem with url rewrite/redirection. I need that www.domain.tld is redirected to www.domain.tld/folder/index.jsp (I'm using resin behind haproxy). Here's my cfg: acl addr1 path_end / redirect location /dnshst/index.jsp if addr1 It work but If I try to login, sometimes work, some time I obtain this url: www.domain.tld/index.jsp (and not www.domain.tld/folder/index.jsp) Have you got ideas on how to do it properly (my backend is in http mode with cookie by SERVERID).

Now I can't use transparent proxy function: if I leave in haproxy.cfg this line source 0.0.0.0 usesrc clientip haproxy say 503 - Service unavailable. If I comment out the line, everything work fine (without transparent proxy). My situation: haproxy with two ethernet device: first one for public IP, sceond one for private IP (192.168.XX.XX) two web server with one ethernet for each one connected to my private network. Have you got ideas or you can provide me examples Hi, I've just set up a transparent proxy with kernel 2.6.28 (the first one with official tproxy support) and haproxy 1.3.15 (the version Debian comes with, but rebuilding the package with the tproxy linux option enabled). Just make sure your backends route their outgoing traffic through the load balancer, since the response packets with the fake address MUST be seen by the load blancer box to undo the transparent-proxy magic.
