Hi,

I would like to introduce reverse ajax to one of my projects.  
Anyone has any opinions on what is the best approach for a serious  
deployment? Comet, Juggernaut, orbitd, cometd, …?

I would appreciate opinions on this issue.

Thanks!

Client-polling is easy enough with periodically\_call\_remote. I don’t  
believe that Rails’ architecture would support Server-pushing. Maybe  
somebody will correct me though.

HTH,

I’ve used juggernaut in a few places now and it works great. Very  
simple to setup and run.

I’d recommend staying away from any library that does this via  
persistent HTTP connections, as those are known to be quite resource  
heavy on both web browsers and web servers.

Thanks for correcting me! This looks _very_ interesting.

Juggernaut is bad:

There is also this cometd stuff:

You could also consider Juggernaut: [http://juggernaut.rubyforge.org/](http://juggernaut.rubyforge.org/)
