Export To Excel Doesn't Work On IE Under SSL

I've been trying to fix something on a secure website (https) which is an Export to Excel button that generates a CSV file. It works on Firefox, Chrome , etc... but not in Internet Explorer. I have changed the headers eliminating the no-cache and also edited the IIS http header configuration setting an expiration date of 1 day. I have no idea of what can be going on and how to solve it. Do you guys have any idea of how to fix this stuff ? I've read so many posts and they're all saying the same thing... caching.

UPDATE 1 :

regarding the error I receive, I receive an IE Alert saying "Internet explorer cannot download filename.aspx from [URL]Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. As I said, it all works out of SSL (https), but the export to excel button, breaks in https.

UPDATE 2:

I'm using these headers:

Response.ClearContent();
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment; filename=" + name.Trim() + ".csv");
Response.AddHeader("Cache-Control", "no-cache");
Response.AddHeader("Pragma", "public");
Response.AddHeader("Content-Transfer-Encoding", "binary");
Response.AddHeader("Content-Length", "2026");
Response.Charset = "";
//Response.ContentType = "application/vnd.ms-excel";
Response.ContentType = "text/csv";
