But it was probably too fast for you to notice...

Break Neck Pizza isn’t called “break neck” for nothing—the request to get your address and

the response from the server happens so fast that you probably don’t have time to start typing

in your order—much less improve your golf game—before your address pops up.

Customer’s

Address

Customer’s

Phone Number

No time for typing or golf here!

The server responds with your

address almost immediately.

As soon as you type in your phone

number, the browser sends a request for

your address to the server.

<script>

var request...

function foo()

{

...

}

</script>

You probably see your address pop

up right away, before you have a

chance to do anything else.
