Agreed, this is unacceptable. A more common scenario is using the User-Agent header (since a lot of servers will perform filtering on this header), and getting your requests denied because they don't know how to deal with multiple headers with the same key.
For anyone looking for a quick fix, you can perform this monkey patch:
import hyper.common.headers
def hyper_monkey(k, v):
yield k, v
hyper.common.headers.canonical_form = hyper_monkey
(Related to #314, but impacts the request side of things)
Because of the way HTTPHeaderMap splits header values on commas into multiple ways, servers may have trouble understanding headers with multiple values. Example:
Output:
Expected output (note the spaces in Accept-Encoding):
The following curl command retrieves the expected output:
This is a minimal example, but I have run into situations where the server (outside of our control) expects the headers to be in a very specific format.
