// This class provides support for dealing with range requests and the
// subsequent partial-content responses. We use sparse cache entries to store
// these requests. This class is tightly integrated with HttpCache::Transaction
// and it is intended to allow a cleaner implementation of that class.
//
// In order to fulfill range requests, we may have to perform a sequence of
// reads from the cache, interleaved with reads from the network / writes to the
// cache. This class basically keeps track of the data required to perform each
// of those individual network / cache requests.
