1944556 - Implement PNA detection in Necko

Status: NEW

(Core :: Networking: HTTP, enhancement, P2)

Description

[Sunil Mayya]

This bug will implement detection of Private Network Access for a Request.
Specifically, we will implement the following for PNA:

• Part 1 Private Network Access is detected in transaction/connection manager and error if :
  • Preflight is not done for this request AND
  • the request is not a CORS-PNA preflight request AND
  • the target address space is less private compared to the triggering principal's address space.
• Part 2 The error is propagated by failing the transaction through call backs in OnStartRequest
• Part 3 A flag to indicate if preflight is successful. This will be used by the transaction/connection manager.
