Question

Hi I need to process a remote .ical file from another server on my own server and hand it back to the requesting user.

So what I need to do is:

• Fetch the file (could do this with urllib2)
• Process the file with some regex (not the question)
• hand it back with a specific header <– my main problem

I’d know how to do this with php:

header('Content-type: text/calendar; charset=utf-8');
header('Content-Disposition: inline; filename=calendar.ics');
echo $ical;
exit;

But how to do the same thing in python?

Well, as with anything web-related, you start with a WSGI application.

def app(environ, start_response):
    calendar = get_processed_file()

    start_response('200 OK', [
        ('Content-Type', 'text/icalendar; charset=utf-8'),
        ('Content-Disposition', 'inline; filename=calendar.ics'),
    ])
    yield calendar

Then to deploy, you use a handler, e.g. plain CGI would be

import wsgiref
wsgiref.CGIHandler().run(app)

See http://www.wsgi.org/ for more materials about WSGI.
