The documentation says that out REST headerParams are response headers that you don't send to the server, but if you don't send the header to the server it complains about a missing non-optional header parameter:

import vibe.d;

shared static this()
{
	auto settings = new HTTPServerSettings;
	settings.port = 3000;
	settings.bindAddresses = ["::1", "127.0.0.1"];
	auto router = new URLRouter;
	router.registerRestInterface(new Rest);
	listenHTTP(settings, router);
}

interface IRest
{
	@headerParam("a", "X-A-Header")
	int getFoo(out string a);
}

class Rest : IRest
{
	int getFoo(out string a)
	{
		a = "hi";
		return 0;
	}
}

Now open http://localhost:3000/foo and you would expect it to return 0 and send back the X-A-Header with hi as value, however it returns this:

400 - Bad Request

Missing non-optional header parameter 'X-A-Header'.
