???
? SYMPTOMS??
? Calling?? InternetSetOption?? (or?? MFC?? CHttpFile::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.????
???
? Another?? solution?? may?? be?? to?? create?? a?? second?? thread?? that?? would?? call?? blocking?? WinInet?? API.?? Closing?? the?? handle?? from?? within?? the?? original?? thread?? will?? cancel?? blocking?? API?? in?? the?? second?? thread.?? Please?? see?? documentation?? for?? InternetCloseHandle?? for?? more?? details.????
