(PowerShell) Bandwidth Throttled Asynchronous HTTP Upload

Demonstrates how to do an HTTP upload asynchronously in a background thread with limiting the rate to an approximate number of bytes/second. The only difference between this example and one without bandwidth throttling is that the BandwidthThrottleUp property is set.

# Specify the page (ASP, ASP.NET, Perl, Python, Ruby, CGI, etc)
# that will process the HTTP Upload.

# Set the BandwidthThrottleUp property to throttle to approx 64K/second
$upload.BandwidthThrottleUp = 65536

# Begin the HTTP upload in a background thread:
$success = $upload.BeginUpload()
if ($success -ne $true) {
    $($upload.LastErrorText)
}

    $("Upload started...")
}

# Wait for the upload to finish.
# Print the progress as we wait...
while (($upload.UploadInProgress -eq $true)) {
    # We can abort the upload at any point by calling:
    # upload.AbortUpload();

    # Display the percentage complete and the number of bytes uploaded so far..
    # The total upload size will become set after the upload begins:
    $([string]$upload.PercentUploaded + "% " + $upload.NumBytesSent + "/" + $upload.TotalUploadSize)

    # Sleep 2/10ths of a second.
    $upload.SleepMs(200)

}

# Did the upload succeed?
if ($upload.UploadSuccess -eq $true) {
    $("Files uploaded!")
}
else {
    $($upload.LastErrorText)
