There is no browser cache issue in production mode because if a file has changed, the minimized hashcode has changed.
In dev mode, we always have to manually force refresh to reset cache.

The MinimizeTransformer could change filenames even in dev mode to concatenate their modification date/size/whatever.
e.g. foo.js => foo.AB4F4==.js where AB4F4== would be ignore
or maybe better if it works foo.js?cache=AB4F4%3D%3D
