Well John,
I'm not a specialist about Cookies, but something is quite surprising in your code
:
-> you call getCookies() method on the request object to retrieve all the cookies
sent by the browser. But, if you want to change the value, you have to overwrite it on
the client, so according to me you necessarily have to call response.addCookie()
method if you want your change to be stored....
Well, just correct me if I'm wrong, but your code should look like
Cookie[] cookie = request.getCookies();
for(int counter = 0;counter < cookie.length;counter++) {
if(cookie[counter].getName().equals("foo")) {
cookie[counter].setValue("1234");
response.addCookie(cookie[counter]);
}
}
regards,
Franck

Objet : setting cookie values
> Hello,
> I am trying to set a cookie value in my JSP page and I just can't seem to get
> it to write to the cookie file. Here is what Im doing:
>
> Cookie[] cookie = request.getCookies();
> for(int counter = 0;counter < cookie.length;counter++) {
> if(cookie[counter].getName().equals("foo")) {
> cookie[counter].setValue("1234");
> }
> }
>
> When I retrieve the value immediately after setting it, using getValue() it
> returns me the correct value which i set (1234), however when i look in the
> cookie file it has not been set. And of course when i move onto other pages
> and check the value it has not been set, it still displays its old value.
>
> One note on this is that the cookie value already exists and so im trying to
> overwrite it with this new value....though i doubt this should be the problem.

> Any help would be appreciated. Thanks in advance.
