Tough Cookie

[Carol Murphy]

Asked by Marilyn in a nitpick:

Do you want a new Cookie or do you want to change the original Cookie that already exists?

Well, I want to change the cookie that already exists, but cookie.setValue(String) doesn't change the value of the cookie. So I just made a new one. Now that works, I just don't like the fact that I can't change the value.

Hi Carol,

I tried to make my cookie code 'elegant' by trying to change a cookie directly. No luck. The solution I came up with is to loop through all the cookies until I find the right one and then change the value.

Yeah, I thought I was doing the same thing, iterating through the Cookie Array until I found the one with the right name and changing the value............ but the value doesn't change. When I simply create a new Cookie with the same name but give it a different value, I get the result I was after. Only my code isn't working quite right yet. The back button allows the user to get right back into the app even though the cookie value isn't right. Perhaps each jsp needs to check the cookie value before it displays?
I'm at the Apple store in WC. I have to work 3 til midnight tonight. We're doing a remodel................... I will contemplate this while I work!

After you change it, do you add it again?

[Carol Murphy]

No. When the logout button is clicked, the cookie gets changed to something that should cause the login page to display. But when I check the value in Firefox's tool menu, the value doesn't change when I use setValue(). It does change when I just make a new cookie.
I think it may have something to do with scope. When using setValue(), the code is inside the for loop. Perhaps that's what's causing the problem. I'm too fried to check it out now. I'll look at it tomorrow.

Duh..........No. If the for loop finds the one I'm looking for and changes its value, I shouldn't have to add it again, should I? Is this simply a scope issue after all? The value is only changed inside the for loop unless I explicitly add the change to the ArrayList? Hmmmm. Must go check this out.

So the value wasn't changed where I thought it would be changed because I wasn't applying the change to the actual thing that gets passed back to the jsp. Hmmmmmmm. Not exactly a scope issue, but I think I get what wasn't working before.
