Bug 87227

your bug report doesn't make sense to me. You're saying that are sending a bunch of headers around and don't accept them back?

Do you have a URL where this happens?
Can you paste the relevant part of your $HOME/.kde/share/apps/kcookiejar/cookies file?

you can go to this site : http://euh.paranoid.nl/cookies.php
you will see 0 cookies available and size 0 when you came
to the site , and after a RELOAD you will get the error.

The cookies are not in the $HOME/.kde/share/apps/kcookiejar/cookies file
I have to change the experation date for that.

Will try that this weekend.

ok , now I set the cookie to last 30 days , and see how my kcookiejar is filling up :

frits@f1667 kcookiejar $ more cookies | grep cookie_  | wc -l
138
frits@f1667 kcookiejar $ more cookies | grep cookie_  | tail -n 1
euh.paranoid.nl      "euh.paranoid.nl"    "/"          1093597093    0 cookie__1            4    Testing+this+cookie+was+Testing+this+cookie+wasTesting+this+cookie+wasTesting+this+cookie+wasTesting+this+cookie+wasTesting+this+cookie+was.

CVS commit by waba: 

Implemented cookie limits, disabled for now.

Too old and will break other sites that require all cookies as shown in comment #6.
