Cool, good to know. This setup would be a bit overkill to me, but good to know how you set things up and how they work. > You are correct that nginx does not support kerberos so you will need > to keep apache.

Just to help someone who would like to go down the same road, this is my apache site config: <Virtualhost *:80> ServerName whatever DocumentRoot /home/myhome/MyHome/public/ ProxyPass /images ! ProxyPass /stylesheets ! ProxyPass /javascripts ! Alias /images /home/myhome/MyHome/public/images Alias /stylesheets /home/myhome/MyHome/public/stylesheets Alias /javascripts /home/myhome/MyHome/public/javascripts ProxyPass / http://127.0.0.1:8000/ ProxyPassReverse / http://127.0.0.1:8000 ProxyPreserveHost on <Directory /home/myhome/MyHome/public> Options ExecCGI FollowSymLinks AllowOverride all Order allow,deny Allow from all </Directory> </Virtualhost> and my haproxy.cfg file (took it from rubyworks): global web server maxconn 500 socket, therefore log 127.0.0.1 local0 user nobody group nogroup defaults log global mode http balance roundrobin maxconn 500 option httplog option abortonclose retries 3 redispatch clitimeout 120000 contimeout 120000 srvtimeout 120000 listen rails :8000 server rails-1 localhost:8001 maxconn 1 check server rails-2 localhost:8002 maxconn 1 check server rails-3 localhost:8003 maxconn 1 check to test I set the clitimeout, contimeout and srvtimeout to high numbers, so I can see how long actions/requests get handled. The "maxconn 1" parameter does exactly what it says (one request per mongrel). I have to test this setup a bit more, and see what haproxy does if a mongrel goes down or is disabled. Thank you all for your feedback. Simon _______________________________________________ Mongrel-users mailing list Mongrel-users@rubyforge.org http://rubyforge.org/mailman/listinfo/mongrel-users
