| # Description: Simple demo to showcase Redis PubSub with EventMachine | |
| # | |
| # Update 7 Oct 2010: | |
| # - This example does *not* appear to work with Chrome >=6.0. Apparently, | |
| # the WebSocket protocol implementation in the cramp gem does not work | |
| # well with Chrome's (newer) WebSocket implementation. | |
| # | |
| # Requirements: | |
| # - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby |
