hapi set header before sending response

Question

In a hapi handler I try to set a header of my response earlier in the code before sending back a view.

reply().header('cache-control', 'no-cache');

{....}

reply.view('myView', myContext);

Do you I have to use the hold method? In that case how do I reuse the response when rendering the view?

Thanks for your help.

/**************** BREAKING CHANGES SINCE HAPI V.17 ****************/

Breaking changes since hapi v.17 real breaking changes most of codes and libraries and apis changed and prev boiler plates or guides cant help much. So you need to look for new articles tagged with hapi v.17

api page: https://hapijs.com/api#response-toolkit

First reply() is not valid and you should use reply.response()

Second in new guides the reply is changed with h its argument so can be named anything but as the guides are using h so you may use h as well.

Third the hold() is not defined and well and its not needed.

Forth the send() is not needed or even not define i think.

And some other changes. Please check the api link above.

so this is part of code I wrote should give some good information. dont care about the whole function just look at the h and the response section

static _json_response(res, request = null, h = null){
        let ret = '';
        ret = JSON.stringify(res);
        if (request == null || h == null){
                return ret;
        }else{
                const response = h.response(ret)
                        .header('cache-control', 'no-cache')
                        .type('application/json')
                return response;
        }
}
