Description

cache server enhancement

BuildStream relies on buildbox-casd for all CAS access. The gRPC REAPI CAS protocol is efficient for low-latency environments but is difficult to put behind a standard CDN

Upstream work to add client-side support for this protocol as a remote in buildbox-casd's proxy mode is tracked here:
