            Bug ID: 259348
           Summary: Multiple in-flight CacheStorage.open calls create
                    duplicate responses in CacheStorageCache
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Website Storage
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: nham at apple.com

Webpages that call CacheStorage.open multiple times in quick succession can trigger a bug in CacheStorageCache::open which cause multiple responses to be stored per URL in the m_records hash map. This can lead NetworkProcess to use large amounts of memory unnecessarily.
