I've made a "flash message" using the alert component that I want to show exactly once when someone successfully updates a resource. So for example if I set a cookie like this:
```
update users set
name = :name,
email = :email
where id = :id;
select 'cookie' as component,
'admin.alert.title' as name,
'User updated' as value;
select 'redirect' as component,
'user.sql?user=' || :id as link;
```
This cookie is correctly set.

And then in the page that it redirects to, I do this:
```
-- clear flash cookie
select 'cookie' as component, 'admin.alert.title' as name, true as remove;
--- display the value
select 'alert' as component,
sqlpage.cookie('admin.alert.title') as title,
'green' as color
where sqlpage.cookie('admin.alert.title') is not null;
```
The alert is correctly displayed, and I can see that the HTTP headers are trying to unset the cookie in the response (expiration date is in the past):

Frustratingly, Firefox and Chrome are both hanging on to the cookie and thus I'm continuing to see the alert. I don't think this is a technical problem with SQLPage because it looks like the correct HTTP header is being sent to remove the cookie, but I just can't wrap my mind around why this isn't working. In desperation I tried this, which *does* work.
```
select 'cookie' as component, 'admin.alert.title' as name, unixepoch() as expires, '' as value;
```
My computer clock is correct, so I am baffled at why `true as remove` doesn't work...
