Web.py
|

------
|

|

`web.py <http://webpy.org>`_ is a minimalist web framework that is somewhere between Django and Flask.
|
||||
The premise of web.py is that it is flexible - code your webapp any way you want it, in just python and python alone.
|

web.py comes with some nifty tools built in, like database connection tools and a mini http server.

For a long period Apache with mod_python was one of the most reccomended
|

ways to deploy Python applications and thus you may see many tutorials
|
||||
about it on the web or in books, however Apache no longer supports
|

mod_python [1]_ and thus this deployment mechanism is strongly discouraged in

favor of WSGI based ones.

Many improvements have been made with mod_wsgi over mod_python for serving

Python with Apache [2]_. If you must run the Apache web server, mod_wsgi is

your best option for running Python, other than proxying to a dedicated WSGI

`Mongrel2 <http://mongrel2.org>`_ is an application, language, and network

mongrel2 protocol and WSGI. This makes it possible to run your python webapp

written with any WSGI compliant framework. Wsgid has built-in Django support but
|
||||
has also a generic way to load your WSGI application object directly. It's

possible to add support for other frameworks through wsgid's pluggable
|

Apploading interface.

Server Best Practices
|
||||
:::::::::::::::::::::
|
||||
|
||||
While Apache will serve your Python application, and many references suggest it,
|
||||
modern best practices suggest against it. With the improvements in mod_wsgi over
|
||||
mod_python, Apache can handle many more requests than before. However, mod_wsgi
|
||||
tends to use more memory than other WSGI solutions [3]_.
|
||||
|
||||
The majority of self hosted Python applications today are hosted with a WSGI
|
||||
server such as :ref:`uWSGI <uwsgi-ref>` or :ref:`gUnicorn <gunicorn-ref>` behind a
|
||||
lightweight web server such as :ref:`nginx <nginx-ref>` or
|
||||
`lighttpd <http://www.lighttpd.net/>`_.
|
||||
server such as :ref:`gUnicorn <gunicorn-ref>`, either directly or behind a
|
||||
lightweight web server such as :ref:`nginx <nginx-ref>`.

||||
