Server sent events doesn't require any change to the network, it's compatible with almost any setup that uses HTTP today. Web Sockets requires that intermediaries support full-duplex connections. Server sent events is compatible with today's HTTP servers. Web Sockets requires new Web Socket servers. Server Sent Events has a variety of features that Web Sockets lacks by design, such as reconnection, event IDs, and the ability to send arbitrary events. Server Sent Events is likely to end up used as the basis for automated data push mechanisms (e.g. updating Web Storage or appcache stores). These differences mean that there will likely be a reason for both to exist for a long time. > Currently, the two documents don't reference each other at all; some > clarification of their relationship in the specs themselves would be > useful, I think.
