Cookies deletion is not working

[Yasmin_lady]

I use a cookie to save the password of a user so that the login goes automatically, without the needing the user to put in the password. but when a user changes his password the system is still taking the old pass word from the cookie. I tried to delete the Cookie usin the following piece of code with no success.

<cfcookie name="Pass" value="0" expires="now">
<cfcookie name="Username" value="0" expires="now">

Can you tell me what am i doing wrong
Many thanks

What version of CF are you using? Can you post the code for the entire page that is doing the delete?

[Yasmin_lady]

Can you post all of your ColdFusion (CFML) code that you are using to try to delete the cookies?
