[PHP] Sockets and Header data

[Todd Cary]

Ever since PHP 3, I have been using Sockets to pass GET and POST information.  Yes, now that there is the caching ability, I no longer need to do it that way, however it has never failed me and since I deal with some high visibility applications, I am reluctant to change.

With my experience limited to GET and POST, I do not know the format of data that is sent via the PHP header() function.  For instance, if I send

 header("Content-type: text/html");
 header("Content-Disposition: filename=myfile");

what is actually sent?

If I send POST data, the data string looks like

POST http://209.204.172.137:80/mysql/php/menu.php
HTTP/1.0 Accept-Language: en-us
Host: 209.204.172.137:80
Connection: close
Content-type: application/x-www-form-urlencoded
Content-length: 21
session_id=1047421540

How would the two header examples above look?

Is there a PHP application that can intercept the Socket stream?
