public static IHttpClientBuilder AddOutgoingGoogleTraceHandler(this IHttpClientBuilder clientBuilder)
Adds an UnchainedTraceHeaderPropagatingHandler to the HTTP client being built,
which will propagate trace information for outgoing requests, made with this client,
when the request being handled by this server is already being traced.
public static IHttpClientBuilder AddOutgoingGoogleTraceHandler(this IHttpClientBuilder clientBuilder, Func<IServiceProvider, IDictionary<string, string>> labelsProvider)
Adds an UnchainedTraceHeaderPropagatingHandler to the HTTP client being built,
which will propagate trace information for outgoing requests, made with this client,
when the request being handled by this server is already being traced.
A function that provides labels that will be added to the outgoing trace.
The function will be called once per handler, on creation, and the labels obtained at that point will be
used for all subsequent requests made through this handler. Note that the scope of the
IServiceProvider argument will share the lifetime of the handler being created.
May be null, in which case no costum labels will be added to the outgoing trace.
