Overriding header, doesn't override

[Skeen]

When overriding the 'Content-Type' in a controller, by doing;

        response.setHeader("Content-Type", "application/json");

It doesn't actually override, it just appends another header to the response;

        Content-Length:23
        Content-Type:application/json
        Content-Type:text/html

The browser thereby interprets everything as html.

Hello,
This is maybe a case problem
You define Content-Type and the default defined is Content-type (with a lowercase t)

I've changed the default to Content-Type since this is more standard
Can you confirm me it's ok?
Maybe we could fix that, using map<string, pair<string, string> > with lowercase strings as keys for the map
