Ah I see...
HTTP allows empty header values AFAIK. HPack supports it also.
Is it considered as a CFNetwork bug? Is it envisioned to update CFNetwork?

If we think CFNetwork will have support for it in the future, we should keep the idea of trimming whitespaces at XHR level and try to find a temporary solution.

Agreed.
