Headers Protocol v2
wu-sheng opened a new pull request #1767: Cross Process Propagation Headers Protocol v2
URL: https://github.com/apache/incubator-skywalking/pull/1767
Cross Process Propagation Headers Protocol v2, a.k.a. sw6 header protocol, is provided in this PR.
## Differences from v1
The major differences of v2 and v1, comes from SkyWalking's evolution, including
1. Mesh and languages are not same always, some info in headers should be optional.
1. BASE64 encoding required.
1. Sampling flag is including.
Read PR for more details. Notice this protocol will be supported from 6.0.0-beta, not the first 6.0.0 release, also the old sw3 header will be supported too.
@adriancole Is this header similar to Zipkin new header?
