In my experience, developers often do this deliberately as a method of
versioning their CSS and JS. They'll append a "random" string (often a
unix timestamp) at deployment time, rendering that particular version
of the resource cachable until the next deployment.

Are you absolutely sure that this isn't what your devs are doing?
Because if they are, you'd be doing *exactly* the wrong thing by
explicitly ignoring the query-string, and may well break the
application during a random deploy, sometime in the future. But
possibly not during *each* deployment, leading to nicely intermittent
bug reports depending on the amount each CSS/JS has changed, and the
state of the user's browser cache :-)

HTH,
