viewing header information

[Jacobb123]

How can view the header information sent by a web page. is it possible? I want to see what header information is sent not by my website but one that I visit.

with php?
You'd need some kind of HTTP client, the Zend Framework one is as good as any:

reqire 'Zend/Http/Client.php';
$client = new Zend_Http_Client('http://google.com');
$response = $client->request();
foreach($response->getHeaders() as $key => $val) {
echo $key.':'.$val."\n";
}

If you just want to see them, then a firefox plugin like Firebug or Tamperdata will show you them.

If you have FireFox, download Firebug (https://addons.mozilla.org/en-US/firefox/addon/1843). It will display all header information for a page along with javascript errors and so on.

If you don't have FireFox, I strongly suggest you try it out.
