It should have been:
req.send_http_header()
Ie., not plural.
Because I had asked you to set the "content_type", in 2.7.X it is necessary
to explicitly trigger the flushing out of the HTTP response headers before
writing back any actual page content. In 3.1.X, the headers are automatically
flushed out the first time you write back actual content. Thus, if you want
code to be portable between 2.7.X and 3.1.X, you need to call the method
req.send_http_header().
The consequences of not doing it in 2.7.X is that if the Apache configuration
isn't setup to send back a default content type if not set in the response
explicitly, then a browser will use the extension appearing on the request
to work out what to do with the response. Most of the time a ".py" extension
means nothing to a browser and it will pop up a dialog asking you to save
the file rather than simply display it.
