InetGet("abort"), @InetGetActive and @InetGetBytesRead have been removed. The following list shows the new functions used to access the old behavior:
InetGet("abort") - Calling the new InetClose() function with a handle returned from InetGet() will abort a download.
@InetGetActive - Calling the new InetGetInfo() function with no parameters returns a count of active downloads.
@InetGetBytesRead - Calling the new InetGetInfo() function with a handle returned from InetGet()will return the bytes read (and more) for a download.
