ASP.NET - What is the easiest generic way to save form data and retrieve it when the user navigates back to the page?
<p>What is the easiest way to save form data and retrieve it when the user navigates back to the page?</p>

<p>We have an application process that consists of several web forms. If the user clicks to go back a step we would like to auto-populate the fields. I am assuming there is a common generic way to do this without having to mess with individual controls - what is it?</p>
