// Test bug 1527293
//
// Summary:
// The purpose of this test is to check that a cache entry is doomed and not
// reused when we don't write the content due to max entry size limit.
//
// Test step:
// 1. Create http request for an entry whose size is bigger than we allow to
// cache. The response must contain Content-Range header so the content size
// is known in advance, but it must not contain Content-Length header because
// the bug isn't reproducible with it.
// 2. After receiving and checking the content do the same request again.
// 3. Check that the request isn't conditional, i.e. the entry from previous
// load was doomed.
