What did you do?
https://play.golang.org/p/yagiRaYwKRk
https://play.golang.org/p/UVW1Hh9O8Gc
What did you expect to see?
I would expect request.AddCookie("name", "value")
followed by request.Cookie("name")
to always return Cookie with name=value
or at least Cookie with same key but previous value.
What did you see instead?
request.Cookie() does not see the Cookie.
Other considerations
Different programming languages / libraries behave differently in cookie parsing. If golang application is acting as "proxy" and adds cookies to the request, backend systems could parse cookies differently.
