We currently attach HTTP cookie headers from LibWeb within Fetch. This has the downside that the cookie IPC, and the infrastructure around it, are all synchronous. This blocks the WebContent process entirely while the cookie is being retrieved, for every request on a page. We now attach cookie headers from RequestServer. The state machine in RequestServer::Request allows us to easily do this work asynchronously. We can also skip this work entirely when the response is served from disk cache. Note that we will continue to parse cookies in the WebContent process. If something goes awry during parsing. we limit the damage to that process, instead of the UI or RequestServer. Also note that WebSocket requests still have cookie headers attached attached from LibWeb. This will be handled in a future patch. In the future, we may want to introduce a memory cache for cookies in RequestServer to avoid IPC altogether as able.
