I've run into a problem where I add a web app to my iPad home screen (iOS 5.0.1 iPad 2), and when I open it it appears to be caching something behind the scenes, independent of Safari.

I've cleared out everything from Safari that's available in Settings (Clear History and Clear Cookies & Data), and when I navigate to the web app with Safari I see the app in its current state. However if I open the home screen bookmark I get the app in a pre-changed state.

I've seen a lot of information about using a cache.manifest to cache resources for offline use, but I'm not sure if that's relevant to this since I would like the exact opposite: cache nothing.

I've gone to the level of not even testing external resources; if I change some arbitrary test string in the body element of my index.html, the home screen bookmark does not show the updated text.

I think I found a workaround:

The new version of the site only appears when the index.html file changes. (the first file to be loaded)

If you leave the index.html and only change some js in other files then the site doesn't load the new version.

How to clear the cache of a websit…, Hi, I've run into a problem where I add a web app to my iPhone home screen (iOS 5.1.1 iPhone4/4s), and when I open it it appears to be  If an app won’t respond, you can force it to close. Force close an app On an iPhone X or later, or an iPad with iOS 12 or later, or iPadOS, from the Home screen, swipe up from the bottom of the screen and pause slightly in the middle of the screen.

Another workaround is to add ?v=1 to your Javascript and CSS links. For example:

<link rel="stylesheet" type="text/css" media="all" href="./css/ipad.css?v=1">    
<script src="./js/ipad.js?v=1"></script>

It seems one doesn't have to update the number when your file has changed, as far as I can tell. Apparently, on an iPad 2 with the latest software update installed, it is enough to just hint at something dynamic.

Hi, I've run into a problem where I add a web app to my iPhone home screen (iOS 5.1.1 iPhone4/4s), and when I open it it appears to be caching something behind the scenes, independent of Safari.

Create a cache.manifest that instructs it never to cache resources referenced by the main html page:

CACHE MANIFEST

# Version 1.0000

NETWORK:
*

Use it in your index.html:

<!DOCTYPE html>
<html manifest="cache.manifest">

Now whenever you change that manifest file -- for example, by increasing the version number in that comment -- the browser will redownload index.html also.

Ensure your page gets reloaded when the cache is updated:

<script>
function updateSite(event) {
    window.location.reload();
}
window.applicationCache.addEventListener('updateready', updateSite, false);
</script>

Comments
  • Interesting. So it doesn't believe anything has changed unless the actual html file changes. Thanks for the tip!
  • Does not refresh the CSS files for me.
  • Not refreshing JS for me.
  • It only works if the index.html does refer to the js script you updated.
  • Thanks a lot, this finished a morning of headaches! Using iphone 5.1.1 and it seems that home screen webapps only update the JS when the html file is changed, so I'm updating the versions as well. (on 4.3.3 it was updating on every load).
  • @Raanan I'm using an iPad and I'm finding that even changing the HTML file doesn't make a difference. I tried over and over and over again. The only thing that got it to refresh was to delete it off my home page then add it again from safari. Maybe this suggestion would have made a difference, but on my appserver (grunt-contrib-connect) I couldn't properly download the files when I added ?&v=1 to the end.
  • I had to call window.location.reload(true) to force a bypass of the caches. It didn't work without true.
  • This is super helpful! This should really be the accepted answer.
  • This might work, but before anything, at least ONE reload has to happen before the ipad sees this new manifest. That reload has to be triggered somehow, and simply changing something on the server's end doesn't help a thing when the ipad is deciding all by itself never to load anything from the server - which is the case by default.
  • I had to add the cache mainfest also to the html parts that I inserted via Ajax. Only method that worked for me. Thanks!
