Question

I get the following error when downloading excel file in SSL site:

Internet Explorer cannot download xxxx.aspx from mysite.com.  
Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later.

After googling, I suspect that it’s the problem of the response header.
I try the solution in this page and set the header:
http://trac.edgewall.org/ticket/1020

            HttpContext.Current.Response.AddHeader("Pragma", "no-cache");
            HttpContext.Current.Response.CacheControl = "private";

But it doesn’t work.
Any suggestions?

Take a look at this article. It’s from the horse’s mouth so to speak 🙂 We actually just faced this same issue when we switched to a full SSL session.
