Survey limits, how do I set up cookies in APEX

Question

I have a survey on apex 3.1 and need to know if there is a easy way to keep the survey people from filling out the survey just one time from just one pc. I thank that their is the use of cookies but I don't know how to set it up.

Answer 1

Hi,
The standard login page contains an example of how to set up cookie during the page submit process:
begin
owa_util.mime_header('text/html', FALSE);
owa_cookie.send(
    name=>'LOGIN_USERNAME_COOKIE',
    value=>lower(:P101_USERNAME));
exception when others then null;
end;If you set a "Before Header" process to something like:
declare
my_cookie OWA_COOKIE.cookie := OWA_COOKIE.get ('MYCOOKIE');
begin
return my_cookie.vals(1);
end;this will return the value of the MYCOOKIE cookie.
However, as the user can delete their cookies, this may, in fact, not be entirely what you need?
One thing could look into would be the owa_util.get_cgi_env() function as this will allow you to retrieve some information about the end-user.
