Some webpages implement Disqus and also have the rather bad policy of adding auto refresh to the page. This result in for example one writing a long answer in a debate and then a refresh comes along – and everything is gone.

Is the comments, written, but not posted, cached somewhere? Is it possible to retrieve?

I have experienced this on various pages. In the current case the debate page was reloaded and a rather lengthy post with a lot of references and long thought out sentences vanished. This page closes the debate during night time, and do a auto refresh of the page when one pass midnight – as such I'm not able to retrieve the debate for another 8 hours.

Other pages implement for example an auto refresh after 20 minutes.

Linux, Google Chrome.
