posted May 4, 2006 2:56 PM I'm sorry, but I am not able to duplicate the problem that you are describing. Using the PageFetch sample, I started dowloading a large file, then unplugged the network cable. As expected the progress bar immediately stopped and 20 seconds later I got a timeout error. |

posted May 5, 2006 10:56 AM Are you running any kind of proxy server? The web control uses the same DLL (WININET.DLL) that IE uses. It's possible that WININET has already gotten a bunch of data before the connection was released and it delivered it to us afterwards. |

posted May 5, 2006 12:29 PM It's still possible that wininet is buffering data. At least that's the best explanation I can think of. |
