Connecting to socket.io forces browsers to clear page cache

[yujiosaka]

Page cache (bfcache) retains the entire page when go back and forward.
It is important especially for Mobile Safari and Android browser to give smooth UX.

However, connecting to socket.io automatically disables page cache.

I created a sample app and wrote details on it's readme.

I wrote workaround to this problem, but is there a better way avoiding this problem?

Workaround:
It's not so good idea, but we circumvent this issue by disconnecting socket before leaving page.

iPhone does not support beforeunload event, so you need to bind click event to all links, which is why it's not so good idea.

We added the following lines with jQuery:

if (/iPhone|iPod|iPad|android/.test(navigator.userAgent)) {
  jQuery('a').click(function() {
    var href;
    href = $(this).attr('href');
    if (href && href.indexOf('#') !== 0 && href.indexOf('javascript:') !== 0) {
      socket.disconnect();
    }
  });
}

Let me know if there is a better solution/workaround for this issue.
