Since http2 header field names must be lowercase ( https://httpwg.org/specs/rfc7540.html#HttpHeaders ) but if curl uses a lower http version the field names are in mixed case. I noticed as on our live system the prev. and next links couldn't be found as with http1.1 they're in the field
Link
instead oflink
. So it makes sense to always make sure they're lower case for consistency.
