            Bug ID: 189760
           Summary: Resource Load Statistics: Relax cap on partitioned
                    cache max age if reloads result in the same bytes
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
          Assignee: webkit-unassigned at lists.webkit.org

We should add logic to achieve the following:
1. Set cache max age cap for prevalent resources to N days.
2. Start every new cache entry with a max age cap multiplier M = 1.
3. When a cache entry for a prevalent resource reaches the age of N*M days, discard it, but hold on to its checksum and M.
4. If the reload results in the same checksum, increase M according to some scheme such as linear or doubling, until it reaches a year.
