Answers 3  up vote 13 down vote accepted  For now, long polling
is probably the best solution. Many big-name sites have long
polling implementations, including Facebook, Google and eBay.
Not everyone has Flash installed/enabled in their browsers. In
the future Web Sockets might be able to do an easier job of it
for us.  Update: As of this writing, the WebSocket API is
implemented in the latest WebKit (Chrome/Safari) and Firefox 4
beta. There is also a public snapshot build of Opera available
for download with an implementation of the API. This means
testing the API is widely available. For more information, see
this answer.  share|improve this answer +1 I like long polling.
The future might be different but I wouldn't go with Flash. –
