Validating email id

Nothing is more annoying to a user who is on a dial-up connection than clicking the Submit button on the form and then waiting for 20 seconds to find out that they didn't enter their password correctly.

The other option for form validation is to put some client-side Java Script or VBScript at the top of the ASP page that checks if the information in the fields is correct.

If the data is incorrect or not valid, you can send back a response stating this.

Some users are not interested in spending enough time to enter the correct information into a form, and in some cases, users might even intentionally enter false information to gain access or get past a certain step in your application's workflow process.

One of the first steps is to understand what validating data means.

When you used server-side validation with ASP 3.0, if something the user entered was wrong, you could repost the form and ask the user to correct the information in that particular field of the form.

Sometimes, you carried the correct input from the other fields back to the form page, and populated the fields for the users so they didn't have to re-enter the same information again.

The bad thing about server-side validation is that it requires trips back and forth to the server.
