I need to validate a field entry against a database without refreshing the page. If there is a duplicate of the entry in the database, I need an alert to pop and tell the person to re-enter another value.
If you database has more than a few records. Just hit the DB, refesh the page, and be done with it. <BR><BR>
Even 1000 100Byte records means that you're now trying to push 100k of data *just* from the DB to the browser *every time* someone loads the page.
