Passing values between web pages

I need to pass a dollar amount from one webpageto another webpage without letting the user modify the values when the 开发者_JAVA百科values are passed between these pages. ie Page 1 (entry page) to Page 2 (confirmation page)

What is the best way to do this?

You could store the value into the Session and retrieve it from the second page.

You can also try on view state if the data is not so critical.
