Most Windows desktop browsers utilize the keyboard combination Ctrl + F5 to force a page specific cache refresh. Mac OS X based browsers tend to use Command + R. Is there an equivalent cache refresh for a single page in Safari running on iOS?

I realize I can manually clear the browser cache, but I'd prefer to only refresh for the page I am currently viewing.

  • Is this what you are thinking of? apple.stackexchange.com/questions/73153/… – bassplayer7 Dec 13 '12 at 20:02
  • @bassplayer7 it is close but not quite the same. Command + R only refreshes the resources for the specific page you are dealing with. Meaning that externally linked JavaScript from a CDN would also be refreshed. This excludes resources which are not referenced. It's a very fine grained control afforded to desktop browsers and is super handy for web development. – ahsteele Dec 13 '12 at 20:08
  • Makes sense. As a web developer, I understand your point ofhow convenient it is. I'm assuming that you already do, but I can't help not mention it - I use this app from Adobe for my mobile work. And, I believe restarting the Safari - cumbersome as it is - is at least more of a refresh then the button. I haven't messed with it enough to know exactly what it is refreshing, though. – bassplayer7 Dec 13 '12 at 20:15
  • Does pushing the refresh button in the address bar not refresh cached content as well? – Gerry Dec 13 '12 at 22:01

Force quit did not work reliably for me in iOS 8. What did is using private mode for testing:

  1. Open the page in private mode (and bookmark it so you can open it later).
  2. When you need to refresh, close browser "tab" (you can stay in Safari and private mode).
  3. Open the page again (use the bookmark you created in step 1).

    Not a great solution, but it seems to be the best that iOS gives us to work with. – Brendan Jul 14 '15 at 17:12

    How do I get to "private mode"? – linuxdan Mar 26 '18 at 19:46
  • In Mobile Safari: tap the icon of two squares, which will show you all open tabs and reveal the "Private" mode button in the bottom left. support.apple.com/en-gb/HT203036 – Matt Sephton May 24 '18 at 18:58

If you have your phone wired to your Apple computer/laptop, with the Safari developer tools open (and active window) you can press:

Command Key + Option + R

If you force quit Safari (click the home button, then double-click the home button, press and hold the Safari icon in the multitasking bar, then tap the red dot), it appears that Safari will clear its cache. But this will clear the entire cache, not just a single page.

You can also clear Safari cookies and data in the Settings app. Under Advanced you can clear data from individual websites, which may work if you know all the sites associated with the web page you want to flush.

    This is not working for me (iOs 7.0.4). – Nabil Kadimi Feb 17 '14 at 18:59

    With iOS 7, you toss the app upwards from the recent/multitasking list to force-quit it. – hotpaw2 Feb 17 '14 at 19:02

    iOS 7.1 here, I checked via Safari's remote developer tools and it seems that the resources are indeed not cached after force-quitting the app (Timelines > Network requests) – bfred.it Jun 12 '14 at 1:55

You can force the device to stop caching files by connecting it to a computer with a cable and enabling Safari developer mode.

  • Enable Web Inspector on the mobile device:
    Settings > Safari > Advanced > Web Inspector
  • Enable Dev tools in Safari on macOS:
    Safari > Preferences > Advanced tab > Show Develop in menu bar
  • Connect the device to the computer
  • Open the dev tools panel for the device from Safari on the computer:
    Develop > Example's iPhone > example.com/page
  • To disable caching, go to the Network tab and make sure the little icon for "no cache" is blue (looks like a cylinder with a crossout through it).
  • Now you should be able to just hit refresh anytime on the iOS device and you will get an up to date non-cached version!

If you're a web developer this is the ideal way to do it because now you have access to the extremely useful full dev tools panel. And you don't have to keep repeating an annoying process if you need to get a fresh version all the time, not just clear the cache once.

If you're just a general user trying to clear their cache, you might want to use one of the other methods here.

Update: You can now connect to the device over WiFi. May still require initial setup with the cable, but you can definitely connect without it after that.

Delete the cached data for a single site by going to Settings > Safari > Advanced > Website Data > Show All Sites.

Tap Edit on the bottom right of the screen, and then scroll in the list or search with the search field to find the website you want to clear). Tap the red - icon next to the site address, and then tap the Delete button that appears.

Return to Safari and reload the page, and all the site's artifacts will be reloaded.

  • This did not work. The items are not clickable on my iPad (iOS 12). – cheeesus Jan 16 at 12:41

On Safari enable the Developer-Mode. Then you can use the following combination to clear the Cache:

Option-Key + Command-Mac-Key + E

I assume, that this will only drop the cache of the site you are on at that moment.

  • Unfortunately, your instructions only apply to the desktop version of Safari. The question was about the iOS version. – calum_b Oct 5 '18 at 20:55

Double-tap the refresh button.

    Does this work for anyone? Double-tap just stops the refresh that I started with the first tap. – Brendan Jul 14 '15 at 17:12
  • Yes this was the only thing that actually worked for me. Not sure if this just kicks safari in the ass but it works. – Ben Rabidou Apr 12 '16 at 20:56

Long press refresh button. iPhone 6

    That brings up a menu with "request desktop site" in Phone 7. – Flimm May 25 '17 at 10:54

you can add random number get to the script or link src like :

<link rel="stylesheet" href="css/main.css?rand=<?=$rand;?>" type="text/css" /> <script type="text/javascript" src="js/main.js?rand=<?=$rand;?>"></script>

this forces Safari to reload the file, cause it thinks it is a different file.

    How does this work from the user side? – nohillside♦ Jul 14 '14 at 8:08

    Append a random parameter to the URL at the top ...?rand=15 – Aaron Digulla Jun 30 '17 at 8:25
  • This is called "cache-busting," which causes the URL-string to be unique as the browser sees it. Thus, it will never find that URL in its cache. (And the host-side simply ignores the GET-parameter completely.) But, this is really not the same thing as what the OP is asking. – Mike Robinson Sep 14 '18 at 14:47
