# A note on distributed tracing:
#
# Although Istio proxies are able to automatically send spans, they need some
# hints to tie together the entire trace. Applications need to propagate the
# appropriate HTTP headers so that when the proxies send span information, the
# spans can be correlated correctly into a single trace.
#
# To do this, an application needs to collect and propagate headers from the
