Is there a best practice way to restrict a web page to only one user at a
time? This is for a business page that is not used often and would be best
if only one person at a time was allowed to access it. Using vb.net version
3.5. Can be accessed from both Intranet and Internet.

Thanks

I agree with Mark. What I want to supplement is, if you have to do so an
option is to use membership and use this method to get the approximate
number of online users.

Membership.GetNumberOfUsersOnline()

You can check it at the begining and redirect user to another page telling
him to wait, if the value is 1. This is the simplest option. If a user is
inactive for 15 mins (by default), he is not recognized as online user.
Therefore another user can access the page.

Please let me know if this can solve this issue.

As this is unusual you may want to start fist by explaining what is the
problem when multiple users are hiting this page. This way, someone will be
perhaps able to suggest how to solve the original issue rather than
implementing a workaround on top of the original issue...

If this is for data updates for example, optimistic concurrency could
perhaps help...

You cannot lock a single page, or at least not easily. You can put the page
in a database, perhaps, and put a lock on the data and then determine
whether or not to show it to another person. There is a problem with that
approach, however. How do you know when a person is no longer viewing a
page. Here are specifics:

1. User clicks another link - You now can free up the resource
2. User closes browser - You have no indicator he left
3. User types in new URL - You have no indicator he left

With #2 and #3, you can wait for session time out, but that locks the
resource for 20 minutes.

Best practice states you should optimistically lock records, meaning you
determine if they are changed when the user submits a change. If this does
not work, and you truly need to restrict to one person, you are best to set
up a windows app (Silverlight is an option for the web) and restrict there.
