Is that link right? You linked to a bug about http client support for Expect: 100-continue, and it looks like a fix was merged in October: <a href="https:&#x2F;&#x2F;github.com&#x2F;golang&#x2F;go&#x2F;commit&#x2F;dab143c8820151538fea908efe54e9625d1bc795" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;golang&#x2F;go&#x2F;commit&#x2F;dab143c8820151538fea908e...</a><p>Or are there still problems that aren&#x27;t mentioned in that issue?
