I've been reading more about the new APIs that are part of HTML5, or are at least lumped into the HTML5 buzz. Today's reading is from Google's HTML5Rocks site, Introducing WebSockets: Bringing Sockets to the Web. I can see that this has a lot of potential. I think there are a couple of products I've worked on recently that do a lot of low-level asynchronous polling. Sadly, WebSockets will be disabled in Firefox 4 starting with beta 8. Let's hope that spec can be amended quickly to solve the proxy server issue that seems to be at the heart of this issue.
