flask - preserve response header

Question

This is how my login method looks like:

def login():
    if request.method == "GET":
        return render_template('user/login.html')
    else:
        jwt_token = "xxxx"
        resp = redirect(url_for('home.index'))
        resp.headers.set('Authorization', "JWT {}".format(jwt_token))
        return resp

This works fine but the Authorization header does not make it to home.index page.

How do I tell flask to preserve this header on every request?

------Edit---------

This works if I add Token to Cookie as resp.set_cookie('Authorization', "JWT {}".format(json_data["access_token"])) but I would like to keep it in the Authorization Header.

If you want to set Authorization header on all requests, you could do something like this:

@app.after_request
def after_request(response):
    my_jwt_token = 'xxxx'
    response.headers['Authorization'] = my_jwt_token
    return response
