public sealed class AttributeContext.Types.Request : IMessage<AttributeContext.Types.Request>, IEquatable<AttributeContext.Types.Request>, IDeepCloneable<AttributeContext.Types.Request>, IBufferMessage, IMessage
This message defines attributes for an HTTP request. If the actual
request is not an HTTP request, the runtime system should try to map
the actual request to an equivalent HTTP request.
The HTTP request headers. If multiple headers share the same key, they
must be merged according to the HTTP spec. All header keys must be
lowercased, because HTTP header keys are case-insensitive.
The unique ID for a request, which can be propagated to downstream
systems. The ID should have low probability of collision
within a single day for a specific service.
