Since you have not specified the *Content-length* field in the http
header, IE is still waiting for data before displaying the result where
Mozilla doesn't. When you close the socket on the server side, IE knows
that no more data will be delivered and then it displays at last the result.

So, just add a *Content-length* header field containing the length in
bytes of the entity that will be sent and your are done.

As someone pointed out, IE does not know the content length, however, you
may not know it either, becouse the page may be dynamic, generaly in the
case of a php server listening to a port.

What you can do is send a chunked output, which is like lots of little
content-lengths,

here is a revised version of your snippet:

$out_clients[$i]['socket'] = socket_accept($ socket_out);
$http_header = "HTTP/1.0 200 OK\r\n" .
"Accept-Ranges: bytes\r\n" .
"Transfer-Encoding: chunked\r\n" .
"Content-type: text/html\r\n\r\n";
socket_write($o ut_clients[$i]['socket'], $http_header);

$http_body = "<html><head><t itle>test</title></head><body><h1> Test</h1>";
chunkWrite($htt p_body);

$http_body = <I>More Stuff</I>";
chunkWrite($htt p_body);

function chunkWrite($out _clients[$i]['socket'], $string)
{
$hxLen = dechex(strlen($ string)) . "\r\n";
socket_write($s ock,$hxLen);
socket_write($s ock,$string);
}

Ooops, change this:
"HTTP/1.0 200 OK"
to this
"HTTP/1.1 200 OK"

Hm, nice idea, but it doesn't work. Same as before: Mozilla works
fine, IE don't want work. But now i get more than a blank page. Now I
get an "Action canceld"-IE error page (sorry, I only know the correct
english name for that page).

Also I added some more prints to my script. This is what my script do
after I opened the URL (http://server:2323) for ONE TIME!!!

---- snipp ----
Create PID-File, PID: 10274
Try to create sockets
OutputSocket created, listing on port 2323
InputSocket created, listing on port 2324
Setup client input and output handlers
Server ready. Waiting for connections...
New OutputClient: xxx.xxx.xxx.xxx :17607 as $pmc->out_clients[0]
Send $hxLen to $socket
Send $message to $socket
Send $hxLen to out_client[0]
Send $message to out_client[0]
New OutputClient: xxx.xxx.xxx.xxx :17608 as $pmc->out_clients[1]
Send $hxLen to $socket
Send $message to $socket
Send $hxLen to out_client[0]
Send $message to out_client[0]
Send $hxLen to out_client[1]
Send $message to out_client[1]
---- snipp ----

You see: I press enter for one time but IE will open two connections.
As little info:

If write data via $socket it's the html-page. If I write it via
$out_client[i], i wrote "<i>New client</i><br>".

Any idea whats wrong?

lg,
Dennis

Sorry, I have been packing ang getting ready for business trip, so I have
not been all here, anyways, I found another mistake on the code I posted:

chunkWrite should read:
function chunkWrite($soc k, $string)
{
$hxLen = dechex(strlen($ string)) . "\r\n";
socket_write($s ock,$hxLen);
socket_write($s ock,$string);
socket_write($s ock,"\r\n");
}

sorry, I didn't understand the rest of your question. I tested this
chunkWrite function with IE, and it apears to work for me.

Okay, than I hope you can help me with my (I hope the last) problem with
this socket story.

I created a signal handler for SIGHUP to shutdown my script on a nice way.
One of the tasks in the shtudown process is to close all sockets.

---- snipp ----
socket_shutdown ($in_socket);
socket_close($i n_socket);
socket_shutdown ($out_socket);
socket_close($o ut_socket);
---- snipp ----

I think there is no mistake (and there is no error message), but if a stop
my script and start it again within a few seconds I got an error while
binding the socket ("Address already in use") and I have to wait some time
(up to more than a minute).

I already tried to "unbind" the socktes

---- snipp ----
socket_bind($in _socket, "0", "0");
socket_bind($ou t_socket, "0", "0");
---- snipp ----

but I got an error (as hoped for). Whats wrong?

lg,
Dennis
