Hi
I want to determine the content type of uploaded file.
File was uploaded by using <input type=file>.
How can I determine the content type?

I don't know if the http-spec does require a mime-type - neverless you can't
and shouldn't trust that a uploaded file is what the user wants you to
believe it is.... so it would be the best to invoke 'file' on your received
file. It has the -i option to give you the mime-type.

For uploading files, your form tag should specify the attribute
ENCTYPE="multip art/form-data"
since that makes the browser send mime-encoded files
with all necessary headers, like "Content-Type".
It depends on the package you are using, how to get at this
header information.
If you are using the CGI module, you will interrogate the
FieldStorage item. For further reference,
http://www.python.org/doc/current/lib/node403.html
might help.
