Description:
------------
If I open a network connection with fsockopen on port 80, then read the first 
chunk of the response with fread, I receive the response headers plus enough of 
the response body to fulfill the read length that I requested.

However, if I do the same thing over port 443, I receive only the response headers 
in my initial fread command, regardless of their length. I don't receive any of 
the response body until I call fread again.

The script below demonstrates this. If you run it as shown, you will see the 
header plus part of the body as response 1, and a continuation of the body as 
response 2. But if you change $connection_port to 443, you will see only the 
header as response 1, with the body starting at response 2.

I repeated this issue on one server running PHP 5.2.13 and another running 5.3.0.

Test script:
---------------
<?php
	$connection_port = 80;

	$source_domain = "www.msgen.com";
	$source_path = "/assembled/home.html";

	$source_host = ($connection_port == 443) ? "ssl://$source_domain" : $source_domain ;
	$request = "GET /$source_path HTTP/1.0\nHost: $source_domain\nConnection: close\n\n";

	$socket = fsockopen($source_host, $connection_port, $error_number, $error_string);
	fputs($socket, $request);

	$response_1 = fread($socket, 4096);
	$response_2 = fread($socket, 4096);
	
	print "response 1:<br />\n".htmlentities($response_1);
	print "<br /><br />\n";
	print "response 2:<br />\n".htmlentities($response_2);
?>

Expected result:
----------------
I would expect fread to return the same results regardless of the port used for 
fsockopen.

Actual result:
--------------
The first instance of fread stops at the end of the headers when using port 443.
