[thelist] Validating Mime Type of Uploads

[Erik Mattheis]

What you would be "validating" is whether the user has the mime type
correctly set up on their box, not anything about the file. If they have
.pdf defined as application-x/Princess Di, that's what their browser will
send. But your server will in turn send whatever settings it has when the
same file is subsequently requested from the server.

What needs to be accomplished by looking at the file's mime type at this
point?

I am
trying to do form uploads, and one of the things I do is validate that
the MIME type is correct.

When I upload either an XLS or PDF, the MIME type is coming back as
applications/octet-stream, instead of application/msexcel or
application/pdf.
