Is there a way to overwrite a pre-existing cookie with new data but leave the expiry date?

[blurredvision]

I'm wanting the ability to overwrite a pre-existing cookie with completely different data and leave the expiry date. Is this possible?

could you just read the current cookie (data and expiry)

then overwrite it (new data + copied expiry)

seems like it should work?

Guess I'll need to learn how to read the expiry date from a cookie. Thanks .

What are you using to interact with the cookie? Scripting language, I mean. I know in ASP.NET you can get/set a cookie's data without changing its ExpirationDate property.

My bad, I completely forgot to mention scripting language. PHP is my weapon of choice here.

Now that the long weekend is over and I'm back to work, I'd like to see if I can figure this out. Anybody know how to copy the expiry date from cookies in PHP?

From what I have read the expiration date is not sent from the browser to the server, only the name/value pairs. Most of the workarounds I saw were to put the expiration date into another cookie.

I haven't seen anything in PHP to set a cookie without altering the expiration date since leaving the expiration date from setcookie tells the cookie to expire with the session.

can I ask why?

cant think of a reason why you would need to this sort of thing, and you got me curious.

From using a packet sniffer more than I've really wanted to I can confirm that the Cookies header sent from the browser does not include the expiration date or the path of the cookie, just the name=value pair.
