But what are the HTTP headers?
In PHP ...
// Send X-JSON / application/json headers and content if
possible.
if (!headers_sent())
{
if (False !== $a_JSON['Header'])
{
$a_JSON['Header']['Queries'] = $a_Query;
$a_JSON['Header']['Session'] = $_SESSION;
header('X-JSON: ' .
json_encode($a_JSON['Header']));
}
if (False !== $a_JSON['Detail'])
{
header('Content-type: application/json');
sort($a_JSON['Detail']);
echo json_encode($a_JSON['Detail']);
}
}
>From that, in JavaScript, I can use ...
response.headerJSON and response.responseJSON
Without the headers, things don't work properly as the browser assumes
it is text or html coming down the line.
