[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.

    • I've put it behind a login for the time being.  I had something like 600,000 requests from just from Alibaba IP addresses that didn't clarify they were bots or scrapers, and so not easy to block using user agent filtering.  I didn't have any issues with bandwidth or accessibility, but that's 600,000 requests just from one cloud provider made to my spinning rust hard drives, that I have to personally pay for when they die, by bots being ran by corrupt mega corporations ignoring my polite requests that they not scrape me and that the information only be accessed by real humans. If any of y'all here were actually using my Kiwix mirror, I have no issue whatsoever creating a username and password for you, just hit me up using one of the methods listed on my personal site and I'll make one for you. https://marcusadams.me
