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:
|
1 2 3 |
<span class="pln">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.</span> |
Or alternatively do it after the file name:
|
1 2 3 |
<span class="pln">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.</span> |
You can check out this link to see how it could work.
