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.
