Implement Network.getResponseBody by routing the request from ProxyingNetworkAgent (UIProcess) to the correct WebProcess's NetworkAgentProxy, which looks up the resource in BackendResourceDataStore and returns content. As part of this work, process-qualify RequestId to prevent collisions across WebProcesses. Work items: - Process-qualify RequestId by prepending process identifier (e.g., "<processId>-<resourceId>") to prevent ResourceLoaderIdentifier collisions across WebProcesses under OOPIF - IPC message from UIProcess to WebProcess (reverse direction from events) - BackendResourceDataStore content retrieval (getTextContent / getBase64Content) - Process routing: determine which WebProcess owns a given requestId - Content eviction policy (maximumResourcesContentSize) - Handle case where WebProcess has crashed (content lost) Radar cross-reference: rdar://143782685 (per-domain Network SI radar)
