Problem Deleting Cookies

[sjickells]

Can anyone help?

I have written a servlet to delete cookies. but it seems not to be
deleting them or only deleting a few of the cookies but not all of
them. Below is an example of my code :

//Set Print Writer
PrintWriter pout = resp.getWriter();

//Get cookie array from HttpServletRequest
Cookie[] cookieArray = req.getCookies();

//Guard statement to check for missing cookies
if (cookieArray != null)
{
// Print a list of all cookies sent by browser
for (int i =0; i< cookieArray.length; i++)
{
Cookie c = cookieArray;

String cname = c.getName();

//Expire the cookie immediately
c.setMaxAge( 0 );

//Send cookie back to the browser to void it
resp.addCookie(c);

pout.println (cname + " Deleted");
}
}
else
{
pout.println ("No cookies present, or browser does not support
cookies");
}

But when I check to see if the cookies are there using another servlet
I get the following

The two cookies above are the main ones I am having problems with.

Anyone any ideas why the cookies are not expiring?
