It's much simpler than that. Try this in test.py:

def hello(req):
     x = "Hello, world!"
     return x

Then go to:


You'll see the text, and the server will send it as

  Content-Type: text/plain; charset=ISO-8859-1

Now add this function:

def hellohtml(req):
     x = """<html>
<title>Hello, World!</title>
<h1>Hello, World!</h1>
     return x

Go to:


It's now HTML, with the appropriate header:

  Content-Type: text/html; charset=ISO-8859-1

Finally, add a function that takes an argument from the URL:

def hellohtmlarg(req, arg):
     x = """<html>
""" % (arg, arg)
     return x

Go to:


You can see that you generally don't need to worry about sending headers 
or importing the apache module with mod_python.publisher. Just construct 
your page as a string and return it. Publisher does the rest for you.

If you need to set special headers, you can do it like this:

  req.headers_out['Pragma'] = 'no-cache'
  req.headers_out['Cache-Control'] = 'no-cache'
  req.headers_out['Expires'] = '-1'

But I prefer to do it in httpd.conf or .htaccess, myself:

  Header set Pragma "no-cache"
  Header set Cache-Control "no-cache"
  Header set Expires "-1"

It's a matter of taste.
