It would be quite helpful if you formatted your question properly.

Answer 1

For the caching-related headers you need the following settings in your Apache config (assuming you're actually using Apache as indicated by your comments to a previous question):

Header Set Cache-Control "max-age=1209600, public, must-revalidate"
Header Set Expires "Thu , 19 Nov 1981 08:52:00 GMT"
Header Set Pragma "no-cache"

Note that these are webserver settings, not Q2A settings.

And when I use cloudflare, will it look the way I want?

I don't know. I don't use Cloudflare. You should be able to test it quite easily, though.
