This would work in most cases, but not in my situation. You see, my case is
that I display a list of entries (notes) from the database in reverse
chronological order of entry. At the top of the form I have a set of fields
to add a new entry. After the entry is added (via the update) it displays
the the new list with the new entry at the top. The user must be able to
add yet another entry if he puts one in and clicks the submit. What I want
to avoid is having an entry there because of the refresh button.
