I use this very method for dealing with validation (though mine returns a HTTP 400 on validation error). Trivial stuff, like a field being required or not, I check on the client; everything else is checked on the server. I've written a small library to plug this into jquery. It's called quaid, and the validation module docs/examples are: http://benogle.com/quaid/validation http://benogle.com/quaid/validation
