post data between controllers

Thanks for your answer.
What I meant is not quite really that.

From the main controller a form allows the user to edit search settings.
Then when submitted, a result controller is called.
Within the result controller, the submit button recalls the same controller to display results according to any choice the user make.
Everything is fine at that point (I mean search controls are refills accordingly to their previous values).

My problem comes when the user clicks on a displayed result which calls another controller containing the same search form.
I hoped that post data would have been transmitted to the controller and thus edit controls but no.

I hope I made myself clearer.
