"post" without form

I'm working on a project currently where I have a page in which you select data using a form with a "submit" button, which uses the "post" method to send said data to an action page which adds it to the DB. All fairly normal so far.

The action file displays nothing to the user and once the data has been added it response.redirects back to the data entry page.

I want the first page to know (be able to find) the DB record just created (eg, by the record ID), but for preference I don't want to put this in the URL. I also don't want to use cookies as it needs to work if users have cookies turned off. I can use the session ID but for preference I'd rather not, at least not as the only method, as I don't want the info to be lost if a session times out / gets terminated.

This is pointing me back to the action file "post"ing the ID back when it redirects, but as it doesn't write HTML, I can't create a form (can I?).

So, is it possible to post the data back given the above constraints?

Thanks for the tip - but is there a way of doing it not using javascript as well? Not that I'm trying to be an awkward so and so...

I'm trying to make the system as resilient as possible regardless of what the user has turned off, be that cookies, javascript, etc.

It may be I have to use cookies if enabled and session ID failing that; if so, fair enough.

Mart, sorry, but that's not 100% true

What you could do is display a submit button on the third page (in my suggested solution) which when clicked will take the user back to the main form.

But there again, that's just plain stupid and me being a bit picky. lol.
However, I reckon it would work and means that Javascript is not required after all.
