post requests

Frank and Jim are onto something. Remember when we talked about the server

decoding the POST data from your request? Once the server opens up the POST

request data, it doesn’t know what type of data it should expect... and servers really

don’t like mysteries. Let’s take a look, and see what happens with the POST data:

The mysterious POST data

<?php

require(‘lib.php’);

function go() {

$myVar = ...

return ...

}

?>

Break Neck server

placeOrder.php

placeOrder.php

?

The server has no idea what

type of data is in this

POST request... is it an

image? text? XML?

Since the server doesn’t know what

kind of data it has, it doesn’t know

how to pass that information on to

the placeOrder.php script.
