Thanks for your quick response.
I changed my javascript function as below :
function connection(){
url = "/comet?nickname="+$F('nickname');
cometXHR.open("POST",url,true);
cometXHR.setRequestHeader('Content-Type','multipart/mixed');
cometXHR.setRequestHeader('Transfer-Encoding','chunked');
cometXHR.send("hello1");
}
This really produces firstly a BEGIN event and secondly a READ event. But how
to push new data from the client now? If I run again this function, a new BEGIN
event will be produced and after that a READ event. I would like to produce
only READ events, something like to send chunk data to server!
Any suggestion?
Regards,
John
