PPS files for read only

I am writing Power Point presentations which I want to
publish on the web in a read only mode, i.e., I want that
only those who know the edit password can edit the
files. I do this by using the Security Options in "save
as" -> tools. After this operation I save files as pps
files.

When one clicks such a pps file on a PC (where the file
is stored) Power Point plays the slide show. When the
same file is being accessed on the web, Power Point first
asks the user to give the edit password or, failing that,
the user is offered the option of opening the file in the
read only mode. Now I would like to configure my web
server so that edit-protected pps files open without this
password-read-only dialogue. How can I do that?

Thank you for any hints that you may be able to provide.

Click to expand...

Here's my guess as to what's happening:

Local PC: registry entries tell Windows to invoke PowerPoint with the /S (show)
option when you doubleclick on a PPS file.

But the web server sends the browser the file along with header info that tells
the browser that "this is a PowerPoint file". It's up to the browser to decide
what to do with the file (try to open it itself as with html, gif, jpg files;
or pass it off to a helper application, which is what it'll do with PowerPoint
files). There's the problem: the web server has no way that I'm aware of to
tell the browser "Send this to PowerPoint but use the /S option to force it
into Show mode"

It may be up to the local user's browser settings and outside your control.
