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) 2187135 1 webkit-bug-importer 2026-03-04 15:53:41 -0800 <rdar://problem/171758262> 2188496 2 bburg 2026-03-09 15:26:26 -0700 Pull request: https://github.com/WebKit/WebKit/pull/60217 2192791 3 bburg 2026-03-23 10:18:35 -0700 Pull request: https://github.com/WebKit/WebKit/pull/61172 2213366 4 ews-feeder 2026-05-22 13:40:50 -0700 Committed 313753@main (ccf6c82ad5c8): <https://commits.webkit.org/313753@main> Reviewed commits have been landed.
