Hello,

PROBLEM: I.E.6 cannot download files when SSL is used.
Server-side: IIS 5.x; ISAPI extension dll that programmatically transmits
files to the client.

Sample client request: "dld.dll?download&id=123&bid=12345".
When using HTTP, it works perfectly. However, when SSL is used, the client
gets an
error:
"Internet Explorer cannot download ...dll?download&id=123&bid=12345 from ...

Internet Explorer was not able to open this Internet site. The requested
site is either unavailable or cannot be found. Please try again later."


There is one difference when SSL is enabled, that seems to be the cause of
the problem. Normally, when download is initiated (user clicks on the link),
I.E. shows a dialog, like:
------------------------------------------------------
[File Download]
....
File name: TestDoc.pdf
File type: Adobe Acrobat Document
From: serverName

Would you like to open the file or save it to your computer?
[Open] [Save] [Cancel] [More Info]
------------------------------------------------------

When SSL is on (the same dll, the same file):
------------------------------------------------------
[File Download]
....
File name: ...dll?download&id=123&bid=1234
File type:
From: serverName

Would you like to open the file or save it to your computer?
[Open] [Save] [Cancel] [More Info]
------------------------------------------------------

It seems I.E. no longer recognizes the file name or the file type.

Thanks, the links helped determining the cause of the problem (SSL +
Cache-control: no-cache header).
