Caching bug in iOS 5 Safari
On some websites, like CNN shown in the video above, when I hit "back" to return to the previous page, instead of getting the previous page I get a version of the previous page that's from some time in the past, as much as a day or so. I've also had this happen on sites like Reddit. Unless Apple included highly advanced tachyon-based time travel functionality in iOS 5, there's some problem between the web server, the cache, mobile Safari, and my eyes that's conspiring to give me pages from the past.
- Go to a web page in Safari
- Tap a link
- Tap the "back" button
You get an older version of the web page you just left.
- Tap the "reload" button
That gets Safari to render the page again. You can also clear the cache. That seems to alleviate the problem, at least for a while.
- Launch Settings
- Tap on Safari
- Tap on Advanced
- Tap on Website Data
- Tap on Remove all Website Data
I haven't tried this in iOS 5.0.1 yet and it may well be fixed in that build, otherwise here's hoping Apple fixes it soon.
