Why does the collector of css and js files on the project work incorrectly?

Question

css

Hello.
I ran into a problem on a live symfony2 project. There is a collector of static files (css and js), on command it minifies files, combines them into one file and names them with a new name.
But for some reason, after each new build, when I go to the changed page in Chrome, the new styles are not immediately applied, I have to refresh the page to apply them. Tell me, has anyone experienced this? What could be the problem?

Browser side caching? try adding the get-parameter v=build version number to the link to the js and css files, and update this number when the files change.
