…ccel-MappingCurrently BinaryFileResponse, when configured with X-Accel-Redirect sendfile type,will only substitute file paths specified in X-Accel-Mapping. But if the providedfile path does not have a defined prefix, then the resulting header will includethe absolute path. Nginx expects a valid URI, therefore this will result in anissue that is very hard to detect and debug as it will not show up in error logsand instead the request would just hang for some time and then be re-servedwithout query parameters(?).
