[Lift] Re: NGinx and sticky sessions
No I'm not using JSESSIONID because in my app (non lift) I'm not using container's session management. But thanks for the HA proxy tip.

Re: [Lift] Re: NGinx and sticky sessions
I'm not sure if you discussed this but based on my experience, the JSESSIONID cookie is used most often in Jetty/Tomcat/J2EE environments for load balancing (over using client IP). I haven't used nginx for load balancing yet but I've used both HAProxy and Varnish in the past. http://haproxy.1wt.eu/download/1.2/doc/architecture.txt alex On Wed, Jan 13, 2010 at 4:22 AM, Timothy Perrett wrote: > To follow up this thread for completeness, I communicated to Marius that he > needs to use: > > http://wiki.nginx.org/NginxHttpUpstreamRequestHashModule > > Which should do what he wants. > > Cheers, Tim > > On 13 Jan 2010, at 12:02, Marius wrote: > > > > > > > On Jan 13, 1:42 pm, Timothy Perrett wrote: > >> Nginx offers weighted round robin requests if memory serves... what does > your config look like?

Re: [Lift] Re: NGinx and sticky sessions
To follow up this thread for completeness, I communicated to Marius that he needs to use: http://wiki.nginx.org/NginxHttpUpstreamRequestHashModule Which should do what he wants.

Tim, Thanks SO MUCH about the info from the offline talk we've had.

The flow I have is this: 1. client sends a login request with not server_id info. 2. LB needs to dispatch to any node 3. The node that responds back is setting the server_id information in the HTTP response header (based on config files info from each node) 4. The next subsequent requests for this session will also include the server_id information received and here is the balancing rules I need. I'm not sure I should use client's IP address because clients may be behind NATs etc. and this may unbalance the cluster. Currently I have no config, so I'm still not sure how to config my case described here. > > Cheers, Tim > > On 13 Jan 2010, at 11:29, Marius wrote: > > > Hi all, > > > Did anyone here used nginx with sticky sessions?
