Thanks Tim.  I tried both and they work!  But I noticed that it
generated one more sql query when a GET request's sent than that when a
POST request's sent.
  <-[1m<-[35mSQL (0.0ms)<-[0m   SELECT name FROM sqlite_master WHERE
type = 'table' AND NOT name = 'sqlite_sequence'

Where is it from and is it possible to skip it?
