Why?
Recently, we introduced the
sourcehash in the user-agent header to help our support team track down exactly where incoming requests originated from.They've reported back to us that this hasn't been as useful as we wanted, so we're going a different direction.
Instead, we're adopting an industry-standard method of persisting a small UUID on disk that we include with subsequent requests. It's easy for users to read this file and it contains no PII. It also honors our existing telemetry opt outs.
It's meant to be lightweight and failure tolerant.
