posted October 4, 2003 4:11 PM Dear Friends, I am using the Dart Web tool from an ASP page to retrieve data from another server. While stress testing, the component consistently hangs after a certain period of time or number of requests. At that time, there are 2 TCP connections to the remote server that are in the close_wait state. One thing that seems odd is that, from what I read, the close_wait state is supposed to occur on the server. Also, I can't post after that point and the connections don't go away until I reboot the server. Thank you for any assistance. |

The Web Tool uses WININET.DLL which Microsoft does not recommend using in am ASP page. This is why we made the WebASP control ( part of the Web Enterprise Tool ). |

posted October 7, 2003 11:18 AM Thank you. I downloaded the trial version of the WebASP tool and it doesn't have the problem. It also performs a lot better. We'll probably move to the WebASP tool. Thank you very much. |
