A superb instance for that is the cache busting URL parameter on JavaScript references: it doesn’t change the content material, however it’s going to power caches to refresh.”
He supplied an instance of how a easy URL like “/path/file” can increase to “/path/file?param1=a” and “/path/file?param1=a¶m2=b“, all probably serving similar content material.
