Push Webpages jquery

Question

Is there a way to push pages on change rather than putting a timer on a webpage to refresh every x mins? I guess what Im trying to do is not refresh an entire page when only a portion of it may have changed. I have seen on FB when an update happens it has message saying new content available.

Perhaps you could MD5 a page then when an update happens the MD5 changes and the page could be checking this. Not exactly push but it would reduce the traffic of an entire page.

Answer 2

One way is to watch for specific keyboard events and/or mouse events and update the page if certain criteria is met within those events.
