Hi,
For those who are waiting for our tutorial on LiteSpeed + Capistrano deployment in a Rails App cluster, please take a look at http://www.litespeedtech.com/support/wiki/doku.php?id=litespeed_wiki:capistrano
Basically, you need to setup sudo permissions and add
sudo "#{lsws_cmd} restart"
to deploy.rb of your Rails application.
Best Regards, George Wang
