Yes, just do "cherrypy.lowercase_api = True"
after you import cherrypy.

Well, if you set "lowercase_api" to True then
you have to use the lowercase 
names

How will you run CP ? Behind Apache ?
The base_url_filter is only needed if you run CP behind
another web server.
Other parameters you might want to consider are:

'server.protocol_version': 'HTTP/1.1',
'server.log_file': xxx,
'server.log_access_file': xxx,
'server.log_to_screen': False, (if you run it as a daemon)

Well, it depends on your traffic and wether or not you have
some pages that 
take a long time to build. If all your pages build very fast
then you can 
probably just use a few threads (3-5). If your pages take a
while and you'll 
have lots of concurrent users then you can use more ...

Sure. Just set "session_filter.storage_type":
"file" and 
"session_filter.storage_path":
"/my_dir"

Check out section "1.4.2. Configuring sessions"
of the CP book: 
http://www.cherrypy.org/trunk/docs/book/html/index.html

> 5. Any other changes that you may suggest?

You might want to override _cp_on_error so that you get an
e-mail when an 
error happens in your application.

Good luck   And
don't worry, there are lots of production CP sites out 
there (including pretty much all my sites) so you're the
first one to go 
down that route 


Remi.
