Returns detailed data for a handle returned from InetGet().
InetGetInfo ( [handle [, index = -1]] )
| handle | [optional] A handle return from InetGet(). | 
| index | [optional] The index for the data to retrieve. If this value is -1 an array containing all of the below data will be returned. $INET_DOWNLOADREAD (0) - Bytes read so far (this is updated while the download progresses). $INET_DOWNLOADSIZE (1) - The size of the download in bytes (this may not always be present). $INET_DOWNLOADCOMPLETE (2) - Set to True if the download is complete, False if the download is still ongoing. $INET_DOWNLOADSUCCESS (3) - True if the download was successful. If this is False then the next data member will be non-zero. $INET_DOWNLOADERROR (4) - The error value for the download. The value itself is arbitrary. Testing that the value is non-zero is sufficient for determining if an error occurred. $INET_DOWNLOADEXTENDED (5) - The extended value for the download. The value is arbitrary and is primarily only useful to the AutoIt developers. Constants are defined in InetConstants.au3. | 
| Success: | the request data. | 
| Failure: | Empty string and sets the @error flag to non-zero. | 
If called with no arguments then the total number of active downloads will be returned.
This function can be called in a loop to query the number of bytes download or to pause until a download is complete.
