Cookie's expires property cannot be inspected

I try to set a cookie in browser ( here chrome ver.41.xxx ) using debugger's console:

> document.cookie = 'cookie1=hans; expires=Fri, 03 May 2020 11:00:00 GMT;'

Then, I inspect the .cookie property:

> document.cookie 
> "cookie1=Hans"

Surprisingly, no expires section! Fiddler also reports the same when I refresh the page:

These are enough for me to believe that expires property is not set. But, I get more surprised when I see the cookie expires using EditThisCookie extension

enter image description here

I tried to set the cookie using JavaScript in my code and exactly the same result!

Question: How can I make sure that the expires property of the cookie is set?

When reading from cookies, you will only be given the value of cookies which are valid for the current host, path, security setup, and time. Short of using a special browser add-on or browsing the file system (neither of which you can do from your own code), there is no way to get this info about a cookie. If it's there, it's not expired. That's just the way the cookie "API" was written.

In response to "How can I make sure that the expires property of the cookie is set?" - if you pass it, it's set. Using a cookie library to improve upon the browser's API can, however, help you get everything set with less fussy string manipulation.
