[Sigia-l] UI Design Question - Client Versus Server Side Validation

[alfred]

I personally make the distinction of 'well-formed' vs 'valid'. Typically
on the client you can determine well-formedness by way of regular
expressions and similar techniques (LUHN check for credit cards for
example).  Valid is typically impossible to tell until the data hits the
server.

So - on the client - well-formulate - on the server - validate!
