Chapter 5

Once a web server gets a POST request, it gures out what type of data it has received,

and then passes that information on to the program in the request URL.

Web servers unencode POST data

<?php

require(‘lib.php’);

function go() {

$myVar = ...

return ...

}

?>

Break Neck server

placeOrder.php

placeOrder.php

phone=[phone]

address=Mary Jenkins

7081 Teakwood #24C

Dallas, Texas 75182

order=1 Large Cheese Pizza

1 order of Breadsticks

1 2-liter bottle of Diet Coke

The server opens up

the POST request,

and decodes the

request data...

...which, for Break

Neck, is the customer’s

information and order...

...and passes the data on

to the program in the

original request URL.

Since this is a POST request, there’s no

data in the actual request URL.

The server takes care of

taking the data from the

request, and turning it

into something a server-

side program can use.
