Cookie Writer: Allow customization of expiration date

[zhouyx]

The cookeWriter feature allow publisher to write cookie on the origin.

Right now, the expiration date is by default set to 1 year. We need to provide a way for publisher's to customize the cookie expiration date.

Proposed configuration

  'cookies': {
    'cookieMaxAge': 365*24*3600,
    'keyValue1': {
      'value': 'QEURY_PARAM(fake1)',
    }
  },

cookieMaxAge accepts a number unit in second. Which is the cookie will be expired after that amount of time.

Put cookieMaxAge: 604800 (604800=606024*7) if one wants the cooke to expire after 7 days.

Thanks for adding this feature. I'm a bit in doubt about how it should be used.

I would write a configuration like these one making the max age configurable:

"cookies": {
    "enabled": true,
    "cookieMaxAge": {
      "value": "$DEFAULT(${cookieMaxAge}, $CALC(86400, 365, multiply, true))"
    },
   ...
  },

reading the implementation of the cookie-writer.js I see that the value is directly converted to a number and the variables are not expanded:

const cookieMaxAgeNumber = Number(inputConfig['cookieMaxAge']);

Would it be possible to set the cookieMaxAge making that custom for the user?

I'm new on this technology so, please, let me know if there is something obvious I haven't considered or if I should send this question in a different channel or GH issue.

Is there an answer to the question from @AlexBenny ?
We need this feature in our setup and it would be great if we could have some progress here.
Thanks!
