Python Flask, how to set content type

by

Try like this:

from flask import Response
@app.route('/ajax_ddl')
def ajax_ddl():
    xml="foo"
    return Response(xml, mimetype="text/xml")

The actual Content-Type is based on the mimetype parameter and the charset (defaults to UTF-8).

Response (and request) objects are documented here: http://werkzeug.pocoo.org/docs/wrappers/
