APEX

Hi,

I've noticed that when you access a page using the Session 0 and that page contains an "htp.init" in a before header process, for some reason the session expires and creates a new one.

I made an example on apex.oracle.com, but first let me explain what've done exactly.

There's two pages. On page 1, I have an item named :P1_COLOR that is assigned the value of an application item :P_RED. This application item is affected in an application process before header that runs only on page 1 (the value assigned is "This is red"). I also have an item that displays the session id using this code:

return :APP_SESSION;

Then, I have a link called "page 2" in the HTML region :

a href="f?p=&APP_ID.:2:&APP_SESSION.:::::">page 2</a

Also, more importantly, on page 1 I have a process before header that sets a cookie:

begin

htp.init;

owa_util.mime_header('text/html', FALSE);
owa_cookie.send(
name => 'MY_COLOR_COOKIE_'||:P_RED,
value => 'test_value',
expires => SYSDATE365,+
path => null,
domain => null );

owa_util.mime_header('text/html', TRUE);

END;

Now if you go in the application normally without session 0, you will see the "This is red" with the session id and when you click on page 2 you will still see "This is red" with the same session ID

But when using the Session 0, you see "This is red" with a session id, but when you click page 2, you don't see "This is red" and a new session ID is created, but the link in the address bar still contains the session 0. Also, if you press BACK and then go on page 2 again, you don't lose the :P_RED value nor the session. There seems to be a problem only the first time around.

Can anyone explain me this behavior? Is it a bug? What is the work around? Because, i know that if you want to set a cookie you need "htp.init".

Note: I 've commented the cookie part of my process and only left the htp.init uncommented and had the same result, that's why I'm saying it is caused by htp.init

Thanks, reginald
