Widgets page stale when pressing the Back button
|Reported by:||willshouse||Owned by:|
For several versions of Wordpress (maybe all of them), I've noticed that the Widgets page can be loaded from cache:
I'm not sure why this is happening, when the page is first loaded headers are sent including no-cache, must revalidate, max-age=0, all of which seems to be done correctly:
However, if I load the widgets page, make a change to the order of the widgets, then navigate to another page, and then use the back arrow to go back to the widgets page, a cached version of the widgets page (pre-change) is loaded. This can be especially troublesome if you spend a lot of time making changes and adding and removing widgets, or widget content, then go back to the page and make another change before you realize that the cached page is loaded, because it will overwrite all the changes that you had just previously spent so much effort on.
