[google-chrome] Disabling Chrome cache for website development

I am modifying a site's appearance (CSS modifications) but can't see the result on Chrome because of annoying persistent cache. I tried Shift+refresh but it doesn't work.

How can I disable the cache temporarily or refresh the page in some way that I could see the changes?

Disable cache in chrome only works when you have dev tools open

One more option for disabling the cache is provided by my 3rd Chrome extension Page Size Inspector that disables the cache exactly the same way as Devtools does.

In addition, the extension quickly reports page size, cache usage, network requests and load time of a web page in a convenient way. Plus its open source at Github.

Until the bug is fixed you could use Clear Cache Chrome plugin and you can also set a keyboard shortcut for it.

After installing it, right click and go to options:

Check Automatically reload active tab after clearing data:

Select Everything for Time Period:

And then you can go to Menu => Tools => Extensions:

Click on keyboard shortcuts at the bottom:

And set your keyboard shortcut, for example Ctrl + Shift +R:

To be clear, the disable cache checkbox in Chrome (v17 here, but since v15 I believe) is not in the main settings UI. It is in the developer tools settings UI.

1. From the browser window's wrench icon menu (prefs menu) choose Tools ? Developer Tools

2. In the developer tools UI that appears, click the gear icon at bottom right.

3. Check the 'Disable cache' checkbox in the Network section.

Using Ctrl+Shift+R to refresh was nice but didn't get everything I needed. still some things wouldn't refresh, such as data stored in js and css. found a solution: a toolbar of google for chrome web developers. After you install the toolbar select options and "reset page".

How about a bookmarklet which changes the page name to prevent the page from cacheing. In Chrome you would create a new bookmark and then paste the code into the URL. Click the bookmark and the page will reload with timestamp to thwart the cache.

javascript:(function(){var idx = location.href.indexOf('?');var d = new Date();var str = location.href.substr(0,idx) + '?version=' + d.getTime();location.href=str; void 0;})();

Not sure what you are using, but if you are using ASP.Net you can do the following which works like a charm:

<link href="@Url.Content("~/Content/Site.css")[email protected]" rel="stylesheet" />

Basically it will automatically append the Date and Time to the end of the file each time it is ran, meaning since the file name is technically different, you will never have to worry about it getting cached again.

Since version 50 (if I remember correctly), the "Disable cache" option was removed from the Devtool Settings. Go to the "Network" tab and there's the "Disable cache" option.

Add this string of code to your and it should do the trick.

<meta name="robots" content="noarchive">

1. Pull up the Chrome developer console by pressing F12 and then (with the console open):

2. Right click (or hold left click) on the reload button at the top of the browser and select "Empty Cache and Hard Reload."

This will go beyond "Hard Reload" to empty the cache entirely, ensuring that anything downloaded via javascript or etc. will also avoid using the cache. You don't have to mess with settings or anything, it's a quick 1-shot solution.

Hey if your site is using PHP then place following little PHP snippet at the beginning of your html page :

   //dev versioning - stop caching
   $rand = rand(1, 99999999);

Now everywhere you load resources like CSS- or JS- files in a script or link element you append your generated random value to the request URL after appending '?' to the URI via PHP:

    echo $rand;

Thats it! There will be no browser that caches you site anymore - regardless which kind.

Of course remove your code before publishing or simply set $rand to an empty string to allow caching again.

I had the same problem, I tried :

• Control Shift R,
• Disable cache in F12
• Control F5.

Then I discovered that using a .appcache manifest for a non https site is deprecated. I removed my site.appcache file and its reference in the html tag and now I'm seeing the latest version of each page!

I was in a situation that the browser load the cache data from disk even I checked it disabled cache (I was using Chrome). All my CSS and JS were loading from server but not the web page. This was happening on both my local and Production.

To fixed it, I need to put an extra param in my URL to force the browser to get the web page from server, even the controller did not need it.

I was using ASP.Net, so here is my example :

//Controller function
public ActionResult Index()
    {
        return View();
    }
//Link
@Html.Action("Index", "Home", new { ts = DateTime.Now.Ticks.ToString()})

The result is, it will generate a link like: http://www.myweb.com/Home/Index?ts=636558555408282209

This is my situation and solution. Hopefully it could help somebody.

There is a chrome extension available in the chrome web store named Clear Cache.

I use it every day and its a very useful tool I think. You can use it as a reload button and can clear the cache and if you like also cookies, locale storage, form data etc. Also you can define on which domain this happens. So can clear all this shit with only the reload button which you anyway have to press - on your chosen domains.

Very very nice!

You also can define a Keyboard Shortcut for this in the options!

Also another way is to start your chrome window in incognito-mode. Here the cache also should be completely disabled.

If you're using ServiceWorkers (e.g.: for Progressive web apps), you'll likely need to check "Update on reload" under Application > Service Workers in dev tools too.

I use (in windows), ctrl + shift + delete and when the chrome dialog comes up, press enter key. This can be configured with what needs to be cleared each time you execute this sequence. No need to have dev. tools open in this case.

Instead of hitting "F5" Just hit:

"Ctrl + F5"

1. F12 to open Chrome DevTools
2. F1 to open DevTools Settings
3. Check Disable cache (while DevTools is open) as shown below:

This is currently on the Preferences tab which is the default. You may need to scroll down. This checkbox has been moved at least a couple times since this question was asked. Last I checked, it was in the middle column at the bottom. If you have it open on a thinner screen and there are 2 columns under Preferences, it may be near the top right. Feel free to update this post if it changes or comment and I'll update the post.

Clearing the cache is too annoying when you need to clear the cache 30 times an hour.. so I installed a Chrome Extension called Classic Cache Killer that clears the cache on every page load.

Chrome Store Link (free) (Now without malware!)

Now my mock json, javascript, css, html and data refreshes every time on every page load.

I never have to worry if I need to clear my cache.

There are about 20 cache cleaners for Chrome I found, but this one seemed lightweight and zero effort. In an update, Cache Killer can now stay "always on".

Note: I do not know the plugin author in any way. I just found it useful.

In the Canary Channel (and maybe the dev and stable channel will follow along) this is to be found as the second option overall on the left hand-side under the "General" section.

In addition to that, there is always the option to switch into Incognito Mode via Ctrl + Shift + N. Even though that unfortunately also ends your session.

Actually if you don't mind using the bandwidth it is more secure for multiple reasons to disable caching and advised by many security sites.

Chromium shouldn't be arrogant enough to make decisions and enforce settings on users.

You can disable the cache on UNIX with --disk-cache-dir=/dev/null.

As this is unexpected crashes may happen but if they do then that will clearly point to a more severe bug which should be fixed in any case.

This might help someone.

I have rigged my Nginx for crazy caching. Thus, disabling cache in network tools and explicitly clearing cache don't work.

A very simple yet boring workaround is, I just open a new Incognito Tab. Surprisingly it works, all the time!

A hard refresh in incognito mode does the trick anytime I wish to reload in the same mode.

In addition to the disable cache option (which you get to via a button in the lower right corner of the developer tools window -- Tools | Developer Tools, or Ctrl + Shift + I), on the network pane of the developer tools you can now right click and choose "Clear Cache" from the popup menu.

I have used the other options described above but I find that the best is to add the following parameter to the startup of chrome.exe.

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disk-cache-size=1 -media-cache=1

I find not disabling media cache is a good idea but it is here for completeness sake.

In actuality I want an option to completely disable the cache, to use the memory for IO instead of my disk (which would make load time 10x faster too!) but I don't think chrome or any browser for that matter has that option yet.

How can I disable the cache temporarily or refresh the page in some way that I could see the changes?

It's unclear which "cache" you're referring to. There are several different methods a browser can cache content persistently. Web Storage being one of them, Cache-Control being another.

Some browsers also have a Cache, used in conjunction with Service Workers, to create Progressive Web Apps (PWAs) providing offline support.

To clear the cache for a PWA

self.caches.keys().then(keys => { keys.forEach(key => console.log(key)) })

to list the names of the cache keys, then run:

self.caches.delete('my-site-cache')

to delete a cache key by name (i.e., my-site-cache). Then refresh the page.

If you see any worker-related errors in the console after refreshing, you may also need to unregister the registered workers:

navigator.serviceWorker.getRegistrations()
  .then(registrations => {
    registrations.forEach(registration => {
      registration.unregister()
    }) 
  })

There are two more options to disable page caching in Chrome for good:

1. Deactivate Chrome Cache in the Registry

Open Registry (Start -> Command -> Regedit)

Search for: HKEY_CLASSES_ROOT\ChromeHTML\shell\open\command

Change the part after ...chrom.exe" to this value: –disable-application-cache –media-cache-size=1 –disk-cache-size=1 — "%1"

Example: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" -disable-application-cache –media-cache-size=1 –disk-cache-size=1 — "%1"

IMPORTANT:

• there is a space and a hyphen after ...chrome.exe"

• leave the path to chrome.exe as it is

• If you copy the line, be sure to check, if the quotes are actual quotes.

2. Deactivate Chrome cache by changing the shortcut properties

Right-click on the Chrome icon and select "Properties" in the context menu. Add following value to the path: –disk-cache-size=1

Example: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" –disk-cache-size=1

IMPORTANT:

• there is a space and a hyphen after ...chrome.exe"

• leave the path to chrome.exe as it is

Chrome's Cache killer is by far the best option. Since the store URL to install cache killer is down, you can download the CRX file here:

https://www.crx4chrome.com/extensions/jpfbieopdmepaolggioebjmedmclkbap/

once the extension file is downloaded, open Chrome -> more tools -> extensions, then drag the CRX file from the File Explorer or your Desktop (depending the location where you downloaded the file) into the chrome window to install the extension.

When this question was asked, Chrome didn't support the Disable Cache feature. But now, you can find the "Disable Cache" feature in Network Tab in Chrome Dev Tools.

Network Tab with Cache Disabled

You can see that all the resources (I have filtered JS resources) have been fetched from network and not loaded from disk/memory cache.

Disable Cache not selected

You can see that when I refreshed the page but didn't select the "Disable Cache" feature, almost all the resources were loaded from Cache.

This works fine for local web development but there are certain limitations that I'd like to highlight. You can stop reading here if the solution discussed so far meets your use case.

Limitations

1. You have to keep the DevTools Open and Disable Cache Selected
2. When you disable the cache, it is disabled for all the resources in that tab. It makes things slow and is inefficient if you want to disable cache for only 1-2 resources

Using Requestly Chrome Extension to disable Cache for particular resources (JS/CSS/Images, etc)

Recently, I stumbled upon https://medium.com/weekly-webtips/how-to-disable-caching-of-particular-js-css-file-84a93d005172 which helped me understand how you can disable cache for specific resources.

The trick here is to add a query parameter to your resource with random value every time the request is made. Using Requestly Query Param Rule, you can add a param like this

URL Contains mywebsite.com/myresource.js
Add param cb rq_rand(4)

rq_rand(4) is replaced by 4 digits random number when a request is made.

Requestly Query Parameter Rule to add random parameter

After adding the rule, JS/CSS files are not cached

Here you can see that "Disable Cache" is not selected and still the resources are not loaded from Cache because of a random parameter (cb - Read it as Cache buster) in the URL.

1. The good thing is you don't need to keep your dev tools open for having this behavior
2. You can keep this permanently ON and your browsing experience won't be affected too.

How to get the Rule

Here is the link using which you can browse & download the rule if you have Requestly installed - https://app.requestly.io/rules/#sharedList/1600501411585-disable-cache-stackoverflow

Disclaimer: I built Requestly but I think this could be helpful to a lot of web developers and hence sharing here.

There is a better and quicker way now (Chrome version 59.x.x.):

Right-click onto the reload-icon (left of the url-field) and you get a drop-down menu, select the third option: 'empty Cache and Hard reload'.

This option is only available when the developer tools are open. (Notice the difference to option 2: 'Hard reload' -cmd-shift-R). No cache emptying here!

If you do not wish to edit Chrome's settings you may use incognito mode for the same results.

I just got caught out but not necessarily due to Chrome.

I am using jQuery to make AJAX requests. I had the cache attribute set to true in the request:

   $.ajax({
        type: 'GET',
        cache: true,
        ....

Setting this to false fixed my problem but this is not ideal.

I have no idea where this data is saved but I do know that chrome never hit the server for a request.
