doPost called twice

I can't seem to figure out why my servlet calls the doPost method twice on each request. I used

log("Entering Contacts.doPost at " + System.currentTimeMillis()); to confirm the problem. It is really frustrating, because the servlet is set to report database errors. Every time I delete a record, the record is deleted, but the phantom second request fails to delete the nonexistent record (obviously). Any help would be appreciated.
