+// 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.
