Preview link cached in CDN

I'm having problems with preview-links in a production environment that is using a CDN.

To reproduce, create a preview link for a piece of content.

Open the preview link an incognito browser.

Then make changes to the content in the first browser.

Reload in the incognito browser.

In my testing this only happened in a production environment. I could track it down to the cache-control header being set to

cache-control: max-age=31269, public

I think there should be an option to change this, in my case to "max-age=0" equivalent to "must-revalidate, no-cache, private"

    Attached is a patch that sets responses from the preview link controller to max-age=0, making them un-cacheable.

    I'm open for better suggestions but in many cases this will be the desired behaviour. The impact on performance should negligible as preview-links are mainly shared in smaller groups

    This seems reasonable.

    Can we convert this to an MR and update test cases to include cacheability checking?
