It would be better to use Certificate Transparency, but the UE SSL module currently expects pinned public keys, and verification using known key hashes is far better than no verification.

- FHttpSharedData is now IHttpConnectionPool. It is a connection pool of configurable size.
- FHttpRequestPool is now IHttpClient. It is a request pool of configurable size and the point at which most behaviors are configured.
- FHttpRequest is now split into IHttpRequest and IHttpResponse. This separation allows requests to be released back to the client for reuse while the response is still being processed.
- FScopedHttpPoolRequestPtr is now THttpUniquePtr. It is used uniformly with the pool, client, request, and response.
- The response body is now handled by IHttpReceiver, with a basic FHttpByteArrayReceiver provided to capture the whole body into an array.
- The response now includes stats about how much time was spent on various parts of the request, as well as how much data was sent and received and at what rate.
- The response supports cancellation at any point before it is complete, and IHttpResponseMonitor is provided to support thread-safe cancellation and waiting without requiring locks around the unique owner of the response.
- The response will be canceled automatically when destroyed through its THttpUniquePtr.
- The client does not directly support blocking on request creation. Blocking creation of requests is now provided by FHttpRequestQueue.
- The HTTP thread now relies on curl_multi_poll, available in newer libcurl versions, to allow immediate waking when a handle needs to be added or removed.

Added nodiscard on the scope lock helpers to prevent such errors in the future.

A cache replay can be created from any program that uses the cache, and can be replayed through any cache graph in any program that uses the cache.
Save a cache replay by adding -DDC-ReplaySave=PathToReplay.ddr to the command line, and compress when saving by adding -DDC-ReplayCompress to reduce replay size by approximately 85%.
Load a cache replay by adding -DDC-ReplayLoad=PathToReplay.ddr to the command line one or more times.
- Modify the cache priority on loaded replays with -DDC-ReplayLoadPriority=Priority.
- For example, -DDC-ReplayLoadPriority=Lowest will queue replayed requests to execute asynchronously.
- Modify the cache policy on loaded replays with -DDC-ReplayLoadAddPolicy=CachePolicy and -DDC-ReplayLoadRemovePolicy=CachePolicy.
- For example, -DDC-ReplayLoadAddPolicy=SkipData will make the replay prefetch into the cache stores earlier in the cache hierarchy.
- For example, -DDC-ReplayLoadRemovePolicy=QueryLocal will make the replay query only remote cache stores.
Filter save or load operations by combining these arguments:
-DDC-ReplayMethods=Get+GetValue+GetChunks will only process requests of the corresponding methods.
-DDC-ReplayTypes=Type1[[at]Rate1][+Type2[[at]Rate2]...] will only process requests of the corresponding types.
-DDC-ReplayRate=Rate will only process Rate% of the requests that do not match one of the type filters.
-DDC-ReplaySalt=Salt configures the salt used to filter by type and rate, which makes them match consistently between sessions instead of being random.
Load a cache replay with the console command: DDC.LoadReplay ReplayPath [Priority=PriorityName]
