Force Browser to Clear Cache

Force browser to clear cache

If this is about .css and .js changes, one way is to to "cache busting" is by appending something like "_versionNo" to the file name for each release. For example:

script_1.0.css // This is the URL for release 1.0
script_1.1.css // This is the URL for release 1.1
script_1.2.css // etc.

Or alternatively do it after the file name:

script.css?v=1.0 // This is the URL for release 1.0
script.css?v=1.1 // This is the URL for release 1.1
script.css?v=1.2 // etc.

How to force browser to clear cache so changes on my website are shown?

You can add ?xxx to the css and js filenames and browsers will reload them whenever xxx changes. You won't need to rename your source files.

i.e.

You may have seen content managers do this, with random strings generated on each session to force a reload on first load, and then cache for the remainder of the session.

Auto clear cache from browser

You have 3 options:

1. Put this in the head section of your html page :

<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" />
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="0" />

This will make your app to not cache anything at all ( at least you can keep it during
development)

2. Use hard refresh for example ctrl+f5 if you are using chrome every time you reload.

3. Use a Cache killer plugin for your browser. There's a bunch of them out there, you just install them and enable them whenever you want.
