1544821 - [network markers] We don't know the Cache value on child processes

Status: NEW

(Core :: Gecko Profiler, enhancement, P3)

Description

[Julien Wajsberg [:julienw]]

It seems that we don't get the cache value for the markers happening on the child processes; we have it properly on the parent process though.

This could be because we use kCacheUnknown in [1], although I don't know if we have access to this data at this location.
Compare with [2] on the parent process.

I think we also miss the "count" value for these markers that are emitted for a cached request.

The bot thinks this bug is a task, but please change it back in case of error.

This is likely only about propagating this information through OnStartRequest from the parent to the child as another argument in this block
