kingpuka Posted April 2, 2005 Share Posted April 2, 2005 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!

0 LAD Posted April 2, 2005 Share Posted April 2, 2005 That would be a security risk if it allows you to do that. You can't do it.

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

0 LAD Posted April 2, 2005 Share Posted April 2, 2005 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.

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

So your website can get information about the person.. Like e-mails address, username, passwords, etc..

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.

0 GatorV Posted April 2, 2005 Share Posted April 2, 2005 It's not possible, like they have told you it's a BIG security risk and the way browsers are programmed you can't delete the cookies, your best bet it's to paste a tutorial to tell the user to clean them..
