New default timeouts in IE7 wininet

The new wininet.dll which comes with Internet Explorer 7 uses new default timeouts:
INTERNET_OPTION_SEND_TIMEOUT
30000 ms
INTERNET_OPTION_RECEIVE_TIMEOUT
30000 ms
The good news is that you can now override these values by calling the InternetSetOption API (zero value seems to indicate infinite wait, see this example).

In previous versions, InternetSetOption didn't work but at least the default values were quite large:
INTERNET_OPTION_SEND_TIMEOUT
300000 ms
INTERNET_OPTION_RECEIVE_TIMEOUT
3600000 ms
