For a particular use case, we are using nginx as a lb (with 'weight's
and 'fail_timeout's as mentioned in the wiki here -
This works great, but we want to add nodes to the lb dynamically ( i.e.
change the 'server' entries, by adding a new entry or delete stale
On quick glance, there is a http upstream module here, -
http://wiki.nginx.org/NginxHttpUpstreamModule , that discusses those
options used in the lb application.
* Is there an api to add server entries / delete entries managed by the
upstream module dynamically ?

** start writing a separate module similar to 'upstream' , that will
provide the api to do so ?
Any other suggestions for dynamically managing the list of servers in
