RE: [PHP] TimeOut

I have tried the following script on WinNT5, Apache/1.3.13-dev, PHP Version 4.0.1pl2 and OpenBSD2.7 Apache/1.3.12, PHP Version 4.0.1pl2 (mod_php4) push.php; ----------8<-------snip-----------8<------start <?php header("HTTP/1.0 200 OK"); header("Content-type: multipart/x-mixed-replace;boundary=ThisRandomString"); print("\n"); print( "--ThisRandomString\n"); print("Content-type: text/html\n"); print("\n"); print( "First update at "); echo date("H:i:s"); print("\n\n"); print( "--ThisRandomString\n"); flush(); sleep(5); print("Content-type: text/html\n"); print("\n"); print( "Second update at "); echo date("H:i:s"); print("\n\n"); print("--ThisRandomString--\n"); ?> ----------8<-------snip-----------8<------end On NT with the header("HTTP/1.0 200 OK"); statement I get an Apache error message; [Sun Aug 06 09:02:47 2000] [error] [client 192.168.0.60] malformed header from script. Bad header=HTTP/1.0 200 OK: f:/program files /novato/maildirector/php.exe I do not get this error on OpenBSD. I then removed the header("HTTP/1.0 200 OK"); statement and now NT and OpenBSD give the following output to the browser(IE5.0); (after a 5 second pause) ----------8<-------snip-----------8<------start --ThisRandomString Content-type: text/html First update at 18:22:47 --ThisRandomString Content-type: text/html Second update at 18:22:52 --ThisRandomString ----------8<-------snip-----------8<------end And the following output to the browser(Netscape 4.6); (after a 5 second pause) ----------8<-------snip-----------8<------start Second update at 18:23:19 ----------8<-------snip-----------8<------end ie I never see the first update at ... part of the output as I would expect. I have also tried it with; header("Content-type: multipart/mixed;boundary=ThisRandomString"); but it make no difference, the behaviour is identical. IE5 does not seem to understand multipart. The multipart mime boundary does not seem to be working properly in Netscape4.6. Any clues as to what is wrong?
