2020657 - Disable RCWN and eventually remove the code

Status: RESOLVED FIXED

(Core :: Networking: Cache, task, P2)

Description

[Valentin Gosu [:valentin] {{ PTO 3 July - 3 August }}]

RCWN adds another code path to nsHttpChannel that is inherently racy.
Recent experiments have shown that even for devices with a HDD the improvement from RCWN might not be that big.
Instead it might be better to remove RCWN and focus on general cache speed improvements instead.
