I was trying out Cookie example from Session Mgmt chapter of HSFJ. What I did was, created a new cookie with key=username and value=xyz. I also did a setMaxAge(5*60); on that cookie object and added that in response. After sending the response, I checked in browser(firefox 3.0) for the cookie. The cookie was present with expiry time as expected i.e 5 minutes after current time. Now, I made a another request to some other servlet where I checked the maxAge for that old cookie (i.e "username"). Surprisingly, getMaxAge() returned -1. I realized that this can be because the browser is sending the cookie in Header as "cookie:username=xyz" which doesn't contain any info about the max age. So, it is giving the max age by default as -1 to that cookie. What I wanted to know is, if there is any way I can find out the original maxAge of the cookie which I had set while creating it in previous response?
