Well, if you want to do that, you'll need some way to save state. The Web is stateless by design. this means that as soon as you have requested a page and received the response, the Web server forgets about you.

For static pages, this is not a problem but it is for pages containing forms and other data.

To save state (the information from the page, in your case), you have a couple of options:

1. Use hidden form fields.
Simply append each new value as a hidden form field

2. Use Cookies
Add your form values to the Cookies collection

3. Use a database
You can store each submitted form in the database. Hoop up a User ID to the database record, so you can see what user submitted what data.

4. Use a text file
Same as the database, but uses a text file instead (only applicable for small sites)

5. Use sessions
You can use ASP Session to store information. This solution doesn't scale well (you can't use it in a web farm (multiple Web servers), so it mostly appropriate for small to medium sized Internet and Intranet sites.

What exactly are you trying to accomplish? Can you elaborate a bit about your current ideas. Not every solution is applicable in every scenario.
