Context Parameters

• KeysHttp.httpRetryBodyCount: The number of retries when a response body stream errors mid-read. Responses are buffered until complete. This has no default, and must be set to a value greater than 0 to enable body retries.
• KeysHttp.httpRetryBodyDelayFallback: The fallback retry delay in milliseconds between body retries. Defaults to 0.
• KeysHttp.httpRetryBodyAllowUnsafe: Allow body retries for non-idempotent methods or non-replayable request bodies. Defaults to false.
• KeysHttp.httpRetryBodyMaxBytes: The optional maximum number of bytes to buffer per attempt. When exceeded, body retries are disabled and the response continues streaming as-is. By default, this is unset.
