One good way to handle this is to include an onClick event handler for 
your button, and kill the submission if it has been clicked once already:

<script>
var submitted = 0;
function onceOnly() {
    return submitted++ == 0;
}
</script>
...
<input type=submit ... onClick='return onceOnly();'>

You could also do it in the onSubmit event for your <form>.

Its *not* the answer. If your using javascript to avoid doubleclicks, because doubleclicks crash the server, then you should be prepared to accept that the server will still crash on daily basis, because if more then one page request is happening, you'll get precisely the same effect. Try this;- from MiscUtils import DBPool In the servlet, where you aquire the mysql connection, replace it with something like;- dbPool = DBPool.DBPool(MySQLdb,5, host="localhost",user="rarara",passwd="rararar",db="rarara") db=dbPool.getConnection() cr=db.cursor() This *should* add a bit of thread safety to it. I'd also use the threading lib to whack thread locks around the db operations just for safety sake. -- Shayne O'Neill http://perth.indymedia.org I know how hard it is for you to put food on your family." ----George W.
