Well,
the first thing you should do is to check if username and password are
empty in client side by using JavaScript, this way you can save
server-time and net-traffic, if you don`t know how to do it, tell me.
If you want to do it in the server, check if when you put nothing in the
textfields, you get null o void string --> "".
If you get "", you only have to check wether you receive a "" in these
fields.
I don't know if you understand me, becouse my english isn't very good,
bat I hope so.
Tell me something, Dani
