How can I add cache control in Flask when I'm rendering a template?

Question

I read this post https://stackoverflow.com/a/23115561/1765681 . It works but it make global. So my admin page get cached. And I don't want that.

For example. If I want to set cache control only to this:

@app.route('/')
def list_posts():
    entries = db_session.query(Entry).order_by(desc(Entry.id)).limit(5)
    return render_template('list.html', entries=entries)

what should I do?

Capture the response from render_template, and then adjust it as necessary.

Like this:

#UNTESTED
@app.route('/')
def list_posts():
    entries = db_session.query(Entry).order_by(desc(Entry.id)).limit(5)
    resp = make_response(render_template('list.html', entries=entries))
    resp.cache_control.max_age = 300
    return resp

cloudfare don't cache it. You know why? – fpilee Jan 25 '16 at 19:13
Nope, but that sounds like a different question. – Robᵩ Jan 25 '16 at 19:30

It seems that is because I'm using flask login, and by default it sets a cookie. And Cloudfare do not cache when a cookie is present. – fpilee Jan 25 '16 at 19:32
