javascript - Cache busting via params -

-

we want cache bust on production deploys, not waste bunch of time off bat figuring out system doing so. thought apply param end of css , js files current version number:

<link rel="stylesheet" href="base_url.com/file.css?v=1.123"/>

two questions: break cache? param cause browser never cache response url since param indicates dynamic content?

the param ?v=1.123 indicates query string, , browser therefore think new path from, say, ?v=1.0. causing load file, not cache. want.

and, browser assume source stay same next time call ?v=1.123 , should cache string. remain cached, server set up, until move ?v=1.124 or on.
