Problem with session dropping/loosing value

[southbeach]

NOTE: PHP based application that uses AJAX to process and render data.

I use $_SESSION to track where a user current course of action is or last action was. The idea is to store content so that if they F5 the page I would retain the information they last submitted and keep pages content in solid state.

Content would change only if (a) user changes it and/or (b) form is submitted and new tabulated results are obtained.

I am stuck using a non *SQL environment using a legacy application so storing session to *SQL is not really an option.

Most confusing is that the $_SESSION holds values such as user credential hash keys that are set upon login in. What I am loosing or not retaining is the "additional" elements

$_SESSION['rates']['request']=$_POST;
$_SESSION['rates']['response']=$ResPonse;

The first is obviously the content of the form as last submitted and ResPonse is the content obtained after form data is processed.

if I do a var_dump just after and/or before, I can see the content as I would expect. When a new page is called and the session is referenced, content is gone! In fact, even without moving from one page to the next, a simple AJAX call to a php script that simply do var_dump($_SESSION); comes back with above session elements gone or not set.

Why or what would cause these to just vanish? No changes to server at all ... since it last worked!!!

Solved!

I found

$_SESSION['abc']='abc'; session_write_close();

then further down

$_SESSION['rates']['request']=$_POST;
$_SESSION['rates']['response']=$ResPonse; 
session_write_close();

It appears that session_write_close() is best used ONCE within the script not as $_SESSION is being set!
