Description:
------------
When trying to open remote file via HTTP protocol, PHP produces warning:

failed to open stream: Resource temporarily unavailable

My Windows system have russian locale, so actualy I have localized error message, but this error is Socket error #10035 "Resource temporarily unavailable".

I have tested same code on FreeBSD system, and this error wasn't occuired.

Registered PHP Streams: php, file, http, ftp, compress.zlib, https, ftps

Reproduce code:
---------------
$f = fopen('http://domain/file'); //series of real URLs and IP addresses was tried
$data = fread($f, 1024);
print $data;

Expected result:
----------------
data of file http://domain/file

Actual result:
--------------

Do you get the error when using fopen() correctly?

Socket error #10035: Resource temporarily unavailable.

This error is returned from operations on nonblocking sockets that cannot be completed immediately.
 [2006-03-30 18:08 UTC] igor at oleinikov dot ru 
I use: $f = fopen($url, 'r');
In first post I was make a misprint.

Disable windows firewall and make sure you are able to connect to this host with `telnet host.com 80`.

Windows Firewall is disabled. Any firewall is disabled.
And "telnet domain 80" connects to host successfuly.
I tryied to connect to localhost.
The error still keep occuiring.

There is something wrong with your setup. Just tested:

<?php
$f = fopen('http://www.php.net/index.php', 'r');
while (!feof($f)) {
	$data = fread($f, 1024);
	print $data;
}
?>

which produced the expected output.
