Designing a New HTTP Disk Cache
The networking team has started the process of designing a new HTTP disk cache. We have lost confidence in our ability to improve the existing disk cache as necessary. We just started, but you can monitor plans as they evolve via this page. Feel free to join the discussion if you have ideas, contact Josh Aas.
