Bug 259348

Summary:	Multiple in-flight CacheStorage.open calls create duplicate responses in CacheStorageCache

Description Ben Nham 2023-07-19 15:14:06 PDT

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.
