=== HandlerInterceptor
This feature is available for all tracer implementations.
Since we want the span names to be precise, we use a `TraceHandlerInterceptor` that either wraps an existing `HandlerInterceptor` or is added directly to the list of existing `HandlerInterceptors`.
The `TraceHandlerInterceptor` adds a special request attribute to the given `HttpServletRequest`.
If the the `TracingFilter` does not see this attribute, it creates a "`fallback`" span, which is an additional span created on the server side so that the trace is presented properly in the UI.
If that happens, there is probably missing instrumentation.
In that case, please file an issue in Spring Cloud Sleuth.
