You should be able to detect whether interference is allowed based on
the response status, shouldn't you? That is, if there is a range
request and the application replies 200 OK, you can change that and
apply the ranges. But if the application replies with 206 Partial
Content then the range has already been applied and the server shouldn't
do anything to it.
