NSURLConnection non-closed stream

Vote count:

0

I have a PHP server that looks similar to this one:

header('Content-Type: text/plain; charset=utf-8');
header('Content-Encoding: none;'); //disable apache compressed

ob_end_flush();
ob_start();
set_time_limit(0);
error_reporting(0);

while(true){

    echo ++$i.PHP_EOL;

    ob_flush();
    flush();

    usleep(250 * 1000);

}

This server never closes the connection, and flushes an incrementing number every quarter second. When opening this page in a browser, it works fine, and the content grows while the page is still loading. This page is served via HTTP.

ATTEMPT #1, STRONGLY PREFERRED TO GET TO WORK

I also have a class that is an NSURLConnection with a timeout set to 0 (it shouldn't have a timeout at all). That class gathers data using the NSURLConnectionDelegate protocol; whenever the server sends data, the function - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data is fired. This works excellently after a connection is closed; if there is a lot of data to be sent, one can track the progress very accurately.

In my case, however, the connection is not closed, and it never will be. Nevertheless, I would like to be notified of each flush. Currently, no method fires at all. The moment I set the PHP script to terminate after a certain period of time, and the connection closes, the data-received method is fired.

Therefore I was wondering: is there a way to be notified about every data transmission?

ATTEMPT #2

My next attempt was using NSInputStreams. I initiated them thus:

self.iStream = [[NSInputStream alloc] initWithURL:[NSURL URLWithString:@"http://localhost/secuchat/lab/socket_test.php"]];
[self.iStream setDelegate:self];
[self.iStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
[self.iStream open];

Yet alas, here, too, the function - (void)stream:(NSStream *)aStream handleEvent:(NSStreamEvent)eventCode is never fired.

Lastly, I would really prefer to somehow get it to work using the first method, for I would like to be able to send some data using POST, and raw sockets would make it much more difficult as opposed to libraries that already offer that function.
