[PHP/Javascrip]Delete cookie set by another domain


Question

I need to be able to use a script on "http://www.domain1.com" that will delete a cookie stored on your computer that was set by "http://www.domain2.com".

I've tried using the following in php:

setcookie ("cookiename","", time()-3600,"/main/","http://www.domain2.com");

but it isnt working. I guess it wont let me delete it from a different site, even though i told it the site it was coming from.

Please help!

That would be a security risk if it allows you to do that. You can't do it.

Okay...hmm...

Then is it possible to delete all the cookies that are stored on your computer using a javascript or php script?

Nope, again, that would be a BIG security risk. Imagine I'm setting up a page that would delete all of the cookies from Amazon on your computer. You can only modify/delete cookies from the same domain that was used to create them.

what is the security risk? You can manually delete cookies from your browser, what is the difference with the script?

well if you can delete a cookie that was set by other domain, then you can modify the cookie, that the other domain sets. So your website can get information about the person.. Like e-mails address, username, passwords, etc..

ah, but you can view that stuff from your browser. (at least in firefox).

Is there a way to clear all the cookies on your computer, using a script of some sort. I don't want to view any of them, just have a button that when clicked will clear all the cookies stored on your computer.

    • Sgt Klinger just sounds wrong. I know he made sergeant before end of show, but will always know him as Corporal Klinger. Very sad to hear of Loretta's passing. She definitely helped make the show what it was. 
    • For some reason, Neowin has now pulled this disclaimer pointing out that this survey is utterly useless since it doesn't track the same user data over time (even though Valve has the real information, of course). What it really tracks, without revealing it, is what games are popular each month, who is too busy to answer a dumb survey from month to month, and which cultures (e.g. the Chinese are primarily on expired W10 machines) are gaming in force from wave to wave on whatever game is in vogue at the time. Therefore, these specific surveys, being voluntary and non-consistent, remain nothing but worthless clickbait garbage. They tell us nothing of useful substance regarding actual trends over time.

    • Microsoft will not prevent Windows 11 24H2 or 25H2 or 26H2 from stopping working on those who do not have NPU. This is something very specific to those who want to use Copilot+, only for content creators. Windows 11 works on all hardware released since 2019. It's been 6 years. Any 6-year-old PC has full support for Windows 11. NPU is already standard on mobile phone CPUs and will now be a new standard on PC and notebook CPUs.
