Safari on ipad2 ios7 does not clear cache or history properly

Hi, sometimes i get a ghost image or what to call it in the safari browser. What happens is that after clearing cache and browserlog i get an image of a previous page after starting safari the next time. It also happens after i close it completely, and not having it running in the background. The image of the previous website is only visible for a second before safari clears the screen and i get the blank/new safaripage to start with. But this leads me to belive that safari is not really clearing the log/cache. Has anyone else experienced this and is there a way to fix it? It's not really a probleme per se, but it does mean safari is not working like it should.

iPad 2, iOS 7.0.2

Same for me but with ipad4 ever since upgrading to ios7. Safari stays cached no matter how many times I clear its cache and so does Chrome browser. I even restartd the iPad. I verified it's cached by plugging the ipad into a macbook and in the 'develop' menu of sarari on a desktop did an 'inspect' and it shows the old html.


The temporary fix is to add random strings to urls during development. For example, append a '?': http://mydevsandbox/myapp?

I have the same issue. IPad 2' IOS 7.0.4. When the device is unlocked and Safari opened there are flickers of pages 1-5 days old even though all web content has been deleted, history empty and all apps closed. Don't know where these "phantom images" (good description, Jolla1) are stored. I also see flickers of old game pages when they are opened, old displays from a fantasy football app.


Would also like to find a thread or tech page with an answer.

I too notice this happening and as anytime I have issues I am both happy and troubled that others are having the same issues. I hope we can work together to achieve a solution to our problem and if not then Apple should address the issue that multiple users are experiencing while using their product.


My first step to resolve the issue was to find a way to clear the cache and found the steps used in the past have been lost in the ios7!update. This is troubling to me because it would seem like a disservice to the user to take away or limit user control over the user data, particularly so since it was previously available in past iOS versions. Thus updating the overall operating system whilst downgrading the users preferences means that we are taking steps backwards in overall user experience. This is not a business practice I would expect from a company such as apple that takes great measures to enhance the user experience from update to update.


Please take note apple, the ball is I'm your court.

This is an obvious UIWebView issue and Apple knows it. It's been confirmed that these issues exist on most versions of the iPad. Both caching and memory handling issues. There have been plenty of posts confirming this in Apples communities and other developer communities around the net. I've also experienced this extensively in my own testing on all iPads but the Air. Which is only because I haven't gotten my hands on one. I've just been flabbergasted by the negative performance differences between iOS 6 and iOS 7.


The most disturbing example of caching not releasing was when a friend of mine embarrassed themselves at the coffee house. He turned on his ipad, and there was a pornographic image on the screen for a second before it refreshed. When the cute bistro girl could see it. What is even more frightening is that EVERY TIME this happens, it's after another session has been established. This can be reproduced with 100% reliability. After the old cache clears it loads the current cached pages and returns to normal. Why are we seeing cache from the session before the current session? Why doesn't this happen to other applications utilizing the UIWebView API? This is a MASSIVE security issue on so many levels, Apple.


Not only is safari having problems clearing page caches, but system memory is not releasing properly either. Multiple open pages with CSS frames will quickly bring the browser to a grinding halt, where it will crash upon closing it and opening it again... After ANOTHER long hang. This coupled with the other CSS issues can be crippling for websites on iPad. What's worse is that the memory leaks and CSS implementation issues crushing browsing performance are present in all apps that use UIWebView.


This has been a problem ever since iOS7 launched last year. Apple what are you doing to fix this? This isn't a minor issue. It happens several times a day and these posts have been showing up for months about every ipad that supports iOS7. I don't have the time to rebuild a custom version of a website JUST to suck some more performance out of your hastily implemented, poorly tested code. What the heck happened Apple? This is completely out of character for you.

I am having the exact same problem (IOS 8.1). Mostly with safari, but also occasionally with other apps as well (words with friends, etc). This happens numerous times a week.


My family and I have noticed this on our ipad version 4, but not on our ipad air or ipad mini.


We are very careful with how we use our pads, and only upgrade over the air (occasionally backing up to local itunes with a cable). Any idea that this could be a hack or virus. It does present a real security issue with safari and other apps as well.


Any useful feedback is greatly appreciated.

Same here! But on iPhone


I have ghost images which sometimes appear randomly when starting or returning to Safari. They last one or two seconds then go away. I can't really define a pattern but it happens quite frequently...

Tried clearing the cache and cookies but I didn't do anything as the problem still occurs.


Apparently this issue has been known for quite some time and everyone is waiting for it to be fixed.

Come on. How hard can it be to ask iOS to delete ALL the files in a specific folder?
