Sometimes when opening too much HINTERNETs w/ InternetOpenUrl() the next InternetOpenUrl()'s calls stucks for a long time & maybe forever (received only 60 & 320 status codes and silence:) ).

There is a limit to how many open connections per server you can have at a time (I think it is 2 by default). You can go in and adjust that limit by calling InternetSetOption and programmatically increasing MaxConnectionsPerServer. This may bog down your bandwidth, however.

Another solution is to queue up requests and execute each one once the previous request has completed.

But will the next 3rd or 4th... InternetOpenUrl() wait (I mean, will it send a status code) until 1st & 2nd are closed? Or it will just fail?
