I'm running epiphany CVS against mozilla CVS, both updated as of 6/02/03.
Under epiphany no cookies ever get saved between sessions, mozilla works fine.

My cookies file in .gnome2/epiphany/mozilla/epiphany/cookies.txt hasn't
updated since Jan 24th this year. 

To reproduce:

- Delete (Or back up) your cookies file
- Open epiphany pointing at a page that sets a cookie [Sample PHP below]
- Close epiphany
- Check cookies file

Under epiphany no cookies.txt file is created, under mozilla the file does
contain the set cookie.

Sample PHP
<?
                                                                          
                                                                   
if (setcookie("mycookie", "value",time()+3600)) {
        echo "Foo succeeded";
} else {
        echo "Foo failed!";
}
                                                                          
                                                                   
?>
