    assuming you're using a db to store the messages you could check for a duplicate entry before creating a new one.

    Or you could redirect after doing the data entry part so the refresh basically doesn't do anything.
    Or a combo, which is my preference. I use a timestamp and primary key combo to see if data should be entered as well as do a redirect after the entry. Covers both the refresh issue as well as user hitting "back" button.

    If this post contains any code, I may or may not have tested it. It's probably just example code, so no getting knickers in a bunch over a typo, OK? If it doesn't have basic error checking in it, such as object detection or checking if objects are null before using them, put that in there. I'm giving examples, not typing up your whole app for you. You run code at your own risk.
