I am running into this weird issue with my .NET Core API download functionality where I append a Content-Disposition header from my controller, but it doesn't end up reaching the client. With some debugging I found the following: I can see the Content-Disposition header in the preview of the content's headers' object, but not in the full overview of the same object, which I don't understand. See the following screenshots:
It also appears I can not use the value of the header in my code. Can anybody help me with this issue?
EDIT: I have found out the header is stored under NonValidated as seen in the bottom screenshot. Now I'm not sure what this means, so any help would be appreciated ! :)
