Pages or Web apps using it may break at any time. See also Bug - Add a deprecation notice for AppCache if service worker fetch interception is enabled. Not as such. One method is to send the appropriate headers when delivering content to force the browser to reload:.
Making sure a web page is not cached, across all browsers. NET specific examples. Another, less clean but sometimes only way if you can't control the headers on server side, is adding a random GET parameter to the resource that is being called:. For static resources right caching would be to use query parameters with value of each deployment or file version.
This will have effect of clearing cache after each deployment. In cache. It is important now that it works in my case Apache just by updating each time the "version" comment. It is also an option to name files with "?
Changing just version 1. Now you just change files and in manifest you have to update version comment. Now visiting index. The parts of solution aren't mine but I've found them through internet and put together so that it works. I had a case where I would take photos of clients online and would need to update the div if a photo is changed. Browser was still showing the old photo.
So I used the hack of calling a random GET variable, which would be unique every time. Here it is if it could help anybody. EDIT As pointed out by others, following is much more efficient solution since it will reload images only when they are changed, identifying this change by the file size:.
A lot of answers are missing the point - most developers are well aware that turning off the cache is inefficient. However, there are many common circumstances where efficiency is unimportant and default cache behavior is badly broken.
These include nested, iterative script testing the big one! None of the solutions given here are adequate to address such common scenarios. Most web browsers are far too aggressive caching and provide no sensible means to avoid these problems.
By adding a unique number after? Alternatively, you can append hash or string version of the current time or Epoch after? Not sure if that might really help you but that's how caching should work on any browser.
When the browser request a file, it should always send a request to the server unless there is a "offline" mode. The server will read some parameters like date modified or etags.
If the etag doesn't validate on server side or the modified date is below the current modified date, the server should return the new content with the new modified date or etags or both. If there is no caching data sent to the browser, I guess the behavior is undetermined, the browser may or may not cache file that don't tell how they are cached. If you set caching parameters in the response it will cache your files correctly and the server then may choose to return a error, or the new content.
This is how it should be done. Using random params or version number in urls is more like a hack than anything.
After reading I saw that there is also a expire date. If you have problem, it might be that you have a expire date set up. In other words, when the browser will cache your file, since it has a expiry date, it shouldn't have to request it again before that date. In other words, it will never ask the file to the server and will never receive a not modified. It will simply use the cache until the expiry date is reached or cache is cleared.
So that is my guess, you have some sort of expiry date and you should use last-modified etags or a mix of it all and make sure that there is no expire date. If people tends to refresh a lot and the file doesn't get changed a lot, then it might be wise to set a big expiry date.
This function is called in all of my pages, so when loading it checks if the localStorage's version value is lower than the current version and does a. I opted for this solution for its simplicity, because only mantaining a single file "versio.
The queryString method is hard to implement and is also cached if you change from v1. In addition to setting Cache-control: no-cache, you should also set the Expires header to -1 if you would like the local copy to be refreshed each time some versions of IE seem to require this. There is one trick that can be used. The browser interprets the whole string as the file path even though what comes after the "?
Force browsers to clear cache or reload correct data? I have tried most of the solutions described in stackoverflow, some work, but after a little while, it does cache eventually and display the previous loaded script or file. Is there another way that would clear the cache css, js, etc and actually work on all browsers?
I found so far that specific resources can be reloaded individually if you change the date and time on your files on the server. Instead of clearing cache on my browsers, I realized that "touching" the server files cached will actually change the date and time of the source file cached on the server Tested on Edge, Chrome and Firefox and most browsers will automatically download the most current fresh copy of whats on your server code, graphics any multimedia too.
I suggest you just copy the most current scripts on the server and "do the touch thing" solution before your program runs, so it will change the date of all your problem files to a most current date and time, then it downloads a fresh copy to your browser:. It took me some time to resolve this issue as many browsers act differently to different commands, but they all check time of files and compare to your downloaded copy in your browser, if different date and time, will do the refresh , If you can't go the supposed right way, there is always another usable and better solution to it.
