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.
Problem
- 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.
Work around
- 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.

Yes that has definitely happened to me too, sometimes the page it loads is 3 or 4 days old.
No such problem here...
Maybe jb problem?
Works fine for me as well, no such problem.
Tried that on iOS 5.0.1 on the CNN page. No issues here. Did the same as the video.
Tried this on the same CNN website. Everything was fine on iOS 5.0.1.
I believe you meant to type "iOS 5.0.1" rather than "iOS 5.1" because the latter doesn't exist, yet.
I've seen this behavior when browsing the forums here on iOS 5 Safari. Look at a new post then hit the back button and the post you're looking at isn't in the list! The strange thing is I didn't notice this behavior until yesterday and I've been using iOS 5 for several weeks now.
Couldn't replicate the "bug." Everything worked normally on my ipad. Maybe the problem is on your end.

This happens to me with tipb all the time on my 4S on iOS 5. Happened with my old 3GS on ios 4 as well.
Noticed this problem in the first week of upgrading to ios 5. Thought it was limited to my unit only. True, reloading the page is the best solution
This is corrected in 5.0.1 as I no longer get this issue in Safari at all.
Same here - on all fronts.

This is also the only page this has happened to me on occasion.

This page is also the only place it has happened to me. Also while posting this comment I received a text and safari crashed for the first time since iOS 3.x

I'm not having this issue with mine either.

This bug isn't new at all. I've gotten it since before 4.0, though I haven't seen it in a while. Might be that one of the 4.x's fixed it and 5.0 brought it back?
Same here.
I have the same problem running on 4.3.3 (jailbroken)
Happens on my (not jailbroken) iPad as well, definately an iOS 5 bug.

I have been having this problem since 4.0!!
THIS ISN'T NEWS!!!! THIS HAS BEEN A BUG IN SAFARI FOR ABSOULTELY AGES!!! THIS ISN'T NEWS
I've noticed this several times since upgrading original iPad to iOS 5. So far I haven't seen it on my iPhone 4S, perhaps because I do less browsing on it. Despite others saying it’s been around since 4.x I've never seen it prior to 5.0.
I've had same problem. Thought it was just me thanks Anthony hope it's fixed by Apple. I also have problem in google search. After google gives me search results and I click on one of them and nothing happens. I have to open in safari to get results.
Like Im_DreCo, I had this problem on iOS4 as well.
Still exists on 5.01 too. Not as frequent, but still there.
Still not fixed in 5.0.1. Too bad.
5.0.1 Still the same problem, also when u make a web app it never updates the images. When i delete all my images and check my webapp it still has all the images on it. This also means it never update the images like the app logo ...
I hope they fix this fast!
This has been appending to me on my iPad 1 since ios5 update. Ios5.01 did not fix. I did not have this issue before iOS 5. I did a complete wipe of iPad thought it was fixed for awhile (about 10 days) but its loading cached pages again. Also, I have blank calendar pages upon opening of Calendar. Crashes haven't begun yet but I'm not hopeful. iOS 5 really sucks.
I see this problem frequently with many different websites. I'm using iPhone 4s with 5.0.1
Same here , which keep on breaking mysite. using back button a page is never reloaded from server. good for simple website, but i think this is silly bug and hard to fix.
I have the same issue with iOS 5.1.1. I have eLearning pages that I created and the "main" pages have modal windows to show videos. Everything works as expected in IE8/9, FF, Chrome Safari, and Opera except for using the back button on the iPad. When "main" page is returned to via the back button, it's modal window video is layered on top of the page, rather than being hidden until called for.
All other browsers on both PC and Mac work fine, the video is not visible when the back button is used, only on the iPad.
This is very similar to this article's issue.
