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=60*60*24*7) if one wants the cooke to expire after 7 days. cc @zikas
