      1 // Test bug 1527293
      2 //
      3 // Summary:
      4 // The purpose of this test is to check that a cache entry is doomed and not
      5 // reused when we don't write the content due to max entry size limit.
      6 //
      7 // Test step:
      8 // 1. Create http request for an entry whose size is bigger than we allow to
      9 //    cache. The response must contain Content-Range header so the content size
     10 //    is known in advance, but it must not contain Content-Length header because
     11 //    the bug isn't reproducible with it.
     12 // 2. After receiving and checking the content do the same request again.
     13 // 3. Check that the request isn't conditional, i.e. the entry from previous
     14 //    load was doomed.
