InfluxDB OSS v2 API endpoints use standard HTTP request and response
headers. The following table shows common headers used by many
InfluxDB OSS v2 API endpoints. Some endpoints may use other headers for
functions specific to those endpoints–for example, the write endpoints
accept the `Content-Encoding` header to indicate that line protocol is
compressed in the request body.
