If I go to web page A, then click on a link to B, then click on “back”, sometimes it takes me back to an older version of A. This happens on this site, with A being the GQ page i.e. http://boards.straightdope.com/sdmb/forumdisplay.php?f=3 and going back to the version a few days ago. Seems to only have started recently (within the past month). Does anyone know what’s going on?
