Hello all, I''m interested in providing some real-time interaction between clients connected to my rails application that is mediated by the server (e.g. chat, im, etc.). The big problem I see with this, is that to keep the interaction from appearing sluggish each client really needs to be polling often, which in turn means the server will be loaded even when users don''t actually care about the updates. What I''d like to do is set a dynamic polling interval so that clients are only checking if I can infer that the user actually cares about getting an update quickly, for example if his/her cursor were in the box for typing a chat message. That leaves other hard problems, but at least means a server can support more than a few users. So, two questions: 1. Has anyone built anything with dynamic polling intervals in rails, and is it even possible without getting into the application code? 2. Has anyone built a good chat or im client in rails that they''d like to show off or share? Thanks, pt. -- Parker Thompson http://www.parkert.com/ 510.541.0125
