/* http_post_simple - do a POST to an HTTP URL and return the values
Copyright GPL 2003 by Mike Chirico <mchirico@users.sourceforge.net>
Updated: Sun Jun 13 13:53:14 EDT 2004
A few things to note with this example:
.. note the \r\n .. it needs a carrage return line feed
"POST /test.php HTTP/1.0\r\n"
"Host: souptonuts.sourceforge.net\r\n"
souptonuts.sourceforge.net ip address is 66.35.250.209
but use the dns name "souptonuts.sourceforge.net"
A note on Content-length
"Content-length: 36\r\n\r\n"
->"mode=login&user=test&password=test\r\n"<-- 36 characters
36 is the length of the string "mode=login&user=test&password=test\r\n"
If the string is changed, then length must be adjusted.
