Please add the option to use the set POST data for URL::downloadToFile.
Another solution would be to check for postData in the “createFallbackDownloader” function. Right now it always passes “false”, but it could simply check if the URL has any post-data set. If the post-data is set, it can simply pass “true”.
This feature request is paramount to customer security as any and all personal information should be transmitted using HTTPS as POST-data. Sending it via the GET method is easily intercepted since the personal information is easily readable in the URL itself.
