1806794 - Support "network.responseStarted" for cached responses

Status: RESOLVED FIXED

(Remote Protocol :: WebDriver BiDi, task, P1)

Description

[Julian Descottes [:jdescottes]]

Handling cached responses for the network.responseStarted event depends on proposed changes for the fetch spec at https://whatpr.org/fetch/1540.html#concept-http-fetch

We have been rediscussing where the trigger should take place for cached response, and most likely this will happen before step 10 of https://whatpr.org/fetch/1540.html#http-network-or-cache-fetch if response is not null

For the initial implementation we will focus on the trigger for non-cached responses (in https://whatpr.org/fetch/1540.html#http-network-fetch)

This fixes two issues:

• the transferred size was missing from cached responseStarted events
• the fromCache flag needs to be read on the initial network event payload from devtools, because relying on the isFromCache logic used to build the addResponseStart payload does not properly detect all cached responses (eg for a cached 301)

Julian, can you please check the upstream CI checks? Something failed for Chrome and as such the PR cannot be merged.

I restarted the jobs, but I see Azure Pipelines (infrastructure/ tests: macOS) failing on several PRs, maybe there is an infra issue?
