BUG: InternetSetOption Does Not Set Timeout Values

 Last reviewed: November 6, 1997
Article ID: Q176420
The information in this article applies to:
  • Microsoft ActiveX SDK, version 1.0
  • Internet Client SDK, version 4.0

SYMPTOMS

Calling InternetSetOption (or MFC CInternetSession::SetOption) with INTERNET_OPTION_SEND_TIMEOUT or INTERNET_OPTION_CONNECT_TIMEOUT does not set the specified timeout values.

RESOLUTION

To work around the problem you can use asynchronous WinInet mode, which prevents the WinInet function call from blocking while waiting for a connection. Please see the Internet Client SDK documentation for more information about using WinInet asynchronously.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

InternetSetOption works for INTERNET_OPTION_RECEIVE_TIMEOUT. The receive timeout option controls how long to wait for incoming data to become available. It does not control how long to wait while connecting to or sending data to the server. If the network is down or the server is not available, a WinInet function call that makes a connection (HttpSendRequest, for example) can potentially block for a long time.
