When the request is sent, I am getting a readyState of 4 with a status of 12030. I know 12030 is a Microsoft specific state code that indicate 12019 http error the connection was not sustained. However, I can't seem to find where my code would be causing this error. If I navigate to the page without using the ajax request, it loads fine. Below is the javascript method and the call line.

Microsoft's knowledge base at http://support.microsoft.com/kb/193625 shows that this code is 12030 ERROR_INTERNET_CONNECTION_ABORTED The connection with the server has been terminated. Googling turned up no help; the people encountering this don't seem to be aware of how network sockets work, so I had to actually figure it out on my own. This happens when the client thinks a connection has been kept open, and the server thniks it is closed. The server has sent a FIN, and the client has responded to that with an ACK. Running "netstat" on the Windows client shows that the connection is in the CLOSE_WAIT state, so IE6 really *ought* to have realized this before trying. This is entirely the client's fault. If you wait about 60 seconds, the Windows OS stack will retire the connection. If you need to support IE6, you have some solutions, in various degrees of ugly: retry the ajax request in case of error code 12030if the browser is ie, send an empty request to the server ahead of each ajax requestbundle up your ajax requests such that the time between them is ( (greater than server_timeout) AND (less than server_timeout + one minute) IE7, fwiw, will issue a RST over the CLOSE_WAIT socket as soon as it realizes it has an outgoing connection to make. That, and the socket will only stay in that CLOSE_WAIT state for about 5 seconds anyway. posted by Dan Weber at 9:49 AM 12 Comments: Anonymous said... Fails a lot on IE7 too (seems to be getting worse if that is possible) - watched it happen after socket went to TIME_WAIT then disappeared. Needed delay of ~15 mins on Windows.As you say, best to retry in the onreadystatechange callback - this seems to work well. 8:55 AM Anonymous said... I agree fully that this is entirely the clients fault and this explains why sometimes the first request seemed to work and then subsequent requests using exactly the same data, fails.FYI, happens most using POST requests and SSL.All is not lost however, I have recently experimented and found a possible
