Understanding The New Wininet Option Internet_option_max_conns_per_proxy
- 08 Jun 2009
The documentation on this is very straight forward (http://msdn.microsoft.com/en-us/library/aa385328(VS.85).aspx). At the time of publishing however the documentation has a slight error. You cannot pass a handle in for the first argument. It must be NULL or the call will return false and GetLastError() will show the error is: ERROR\_INTERNET\_INVALID_OPERATION.
The default value for this option is 4 connections.
