Web Browser Close Event

[MikeZ]

I know this is an ASP.NET question, but I know some experts can help me in
this newsgroup:

I have an asp.net web page, I need to push indefinite live video stream to
web Brower, and here is the code:

''''''''''''''''''''''''''''''''''''''''''''''
protected void Page_Load(object sender, EventArgs e)
{
while (true)
{
tmpArray = GetMethod();
Response.BinaryWrite(tmpArray);
Response.BinaryWrite(MJPGHeader);
Response.Flush();
}
}
''''''''''''''''''''''''''''''''''''''''''''''''

It works fine. But when the WebBrowser closed, APS.NET still loops inside of
the Page_Load Event, and never come out.

My question is: How can I exit Page_Load subroutine after client web browser
closed. It is strange that No exception throwed in Response.BinaryWrite()
when client closed.

Thanks

You can't do that without some javascript code, because OnUnload is a
client-side event.

However you can validate this using the session state or a client-side
cookie during the loop and skip the process.

David, I don't think client side Javascripts can do anything on server side
loop. I will test the Session_End event in Global.asax file.
