Setting headers
~~~~~~~~~~~~~~~
To set a header in your response, just treat it like a dictionary::
>>> response = HttpResponse()
>>> response['Pragma'] = 'no-cache'
Telling the browser to treat the response as a file attachment
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To tell the browser to treat the response as a file attachment, use the
``mimetype`` argument and set the ``Content-Disposition`` header. For example,
this is how you might return a Microsoft Excel spreadsheet::
>>> response = HttpResponse(my_data, mimetype='application/vnd.ms-excel')
>>> response['Content-Disposition'] = 'attachment; filename=foo.xls'
There's nothing Django-specific about the ``Content-Disposition`` header, but
it's easy to forget the syntax, so we've included it here.
