MostMinimalRequestHandler

Here is the most minimal request handler possible:

   1   def handler(req):
   2       return 0

The server will respond with something like this (depending on its configuration):

  HTTP/1.x 200 OK
  Date: Sat, 02 Dec 2006 17:29:23 GMT
  Server: Apache/2.2.3 (Unix) mod_ssl/2.2.3 OpenSSL/0.9.7g
  Pragma: no-cache
  Cache-Control: no-cache
  Expires: -1
  Keep-Alive: timeout=5, max=100
  Connection: Keep-Alive
  Transfer-Encoding: chunked
  Content-Type: text/html;charset=utf-8

A request handler must contain a handler() function that takes the request object as an argument:

   1   def handler(req):

It must then return a status code, in the form of an integer:

   1       return 0

In our example, we used zero (0). In subsequent examples, you may see the value of apache.OK returned. This constant, mod_python.apache.OK, is simply defined as zero (0).

This example assumes an understanding of how to define a request handler for a directory or location, a topic which will be discussed elsewhere.
