Best way to not allow more than one user on page.

[bcsheridan]

Do not want another user editing a record on a page when another user is on that page.  Any ideas on the approach I should use?

Please provide more information. What you describe is the normal, default situation anyway.

A thousand of us have opened a page. Our browsers each caches a copy of the page. So, in normal circumstances, one is not really on the page. If the 1001st client were to open the page and edit the record, we wouldn't be aware of the change till we refresh or revisit the page.
