File downloads in IE6.0 under SSL

[Steven]

Long story short I am unable to download a file using Response.BinaryWrite
running under SSL and I am seeking any advice anyone may have.

See the thread titled "Behaviour difference on IIS 5.x and 6.0" at
http://msdn.microsoft.com/newsgroups/managed/default.aspx?dg=microsoft.public.inetserver.iis&lang=en&cr=US dated 9/17/2006

Hi,

Is it possible that your web page is sending HTTP header
"Cache-control:no-cache" or "Pragma:no-cache"?

"Internet Explorer Cannot Download" Error Message When You Use an HTTPS URL
to Open an Office Document or PDF File
http://support.microsoft.com/kb/812935/

I can reproduce this issue by adding following code:

Response.Cache.SetCacheability(HttpCacheability.NoCache);

Please reply to let me know whether or not this suggestion answers your
question.

Sincerely,

Walter, your correct. This was preventing the download and now my web form
works just fine. I removed this from the web form during testing with no luck
and I removed it from the base page however it was defined twice in the base
page. Once all references were removed it worked fine.

I still find it stange that under IE6 it did not work at all and with
FireFox 1.5 the download worked perfectly.

If you take a look at http://support.microsoft.com/kb/812935/, it's a bug
in IE 6.0 sp1. It only occurs when "Do not save encrypted pages to disk" is
selected in IE and server sends "Cache-Control: No Cache" or
"Cache-Control: No Store".

The KB has a hotfix for IE6. Without the hotfix, we can workaround it by
either unselect the option in IE or server doesn't set the Cache-Control
header using "No Cache" or "No Store".
