File Downloader won't work on HTTPS

We are in UAT phase of a critical project and cannot release to the client for testing becuase of this problem. Can anyone suggest a solution:

When user selects Save to Disk option on our site, this puts files from a database to a location on the web server. The File Downloader (version 2.0.10) component is then invoked and should fetch the file list. But the file list pop-up does not display at all. As a result we cannot download files to the user PC.
The license is properly registered.

NB: This code is working 100% in the QA environment (which does not use HTTPS). Also, we use Image Uplader (version 5) on this site with no issues.


Code snippet below:

Extract from FileDownloader.aspx
Javascript Function to handle FileDownloader Steps:

function FileDownloader_DownloadStep(Step)
{
var htxtSessionFolderPath = document.getElementById("htxtSessionFolderPath");
//The file list is going to be downloaded
if (Step == 2)
{
//Change the path to the server script if necessary
getFileDownloader("FileDownloader").setFileList("./GetFileList.aspx?SessionFolderPath=" + htxtSessionFolderPath.value);
}
else if (Step == 11)
{
window.location.href = "DeleteFileList.aspx?SessionFolderPath=" + htxtSessionFolderPath.value;
}
else if (Step == 1)
{
window.close();
}
}

HTML code to display FileDownloader control:
<script type="text/javascript">
//Create JavaScript object that will embed File Downloader to the page
var fd = new FileDownloaderWriter("FileDownloader", 122, 44);

//For ActiveX control full path to CAB file (including file name) should be specified
fd.activeXControlCodeBase = "../FileDownloader2.cab";

fd.activeXControlVersion = "2,0,10,0";

//Set the Download button text
fd.addParam("ButtonDownloadText", "Download files");

//Set license key
fd.addParam("LicenseKey", "73020-2AB8A-00000-0AFD8-92C29;73020-10000-97D4E-A97DD-03D7A");

//The following listener will perform some actions when the file list is about to be downloaded
fd.addEventListener("DownloadStep", "FileDownloader_DownloadStep");

//The following listner will be raised when the whole download process is completed.
fd.addEventListener("DownloadComplete", "FileDownloader_DownloadComplete");

//fd.addEventListener("Error", "onError");

//Tell File Downloader writer object to generate all necessary HTML code to embed File Downloader into the page
fd.writeHtml();
</script>

Extract from GetFileList.aspx.cs
Code behind to generate file list for Downloader:

strBasePath = Server.MapPath("");
strBasePath = strBasePath + "\\";

Response.ContentType = "text/plain";
Response.Charset = "UTF-8";

//Check if the selected subfolder exists
if (Directory.Exists(strBasePath + strFolderPath))
{
DirectoryInfo objDir = new DirectoryInfo(strBasePath + strFolderPath);
//Iterate through all files in the subfolder and build a file list
foreach (FileInfo objFile in objDir.GetFiles())
{
if (objFile.Name.Contains(Request.QueryString["SessionFolderPath"]))
{
//Add the MIME type, the size, and the name for saving
Response.Write("*/* | " + objFile.Length + " | " + objFile.Name + " | ");
//Add the URL to the file and the CRLF combination
Response.Write(EncodeFileName(objFile.Name) + "\r\n");
}
}
}

Hello,

Sorry I did not catch, does your deployment scheme meet these requirements?

Hello Sylvain,

Infortunately the update will not be available in the nearest future. We plan to release next version of File Downloader in about 2 months.

I am really sorry for that.

Hello Sylvain,

Okay, I just talked to development team. The update will be available by 15-17, March. Unfortunately there is no workaround for this problem.
