- Python Paste
Python Paste, often simply called paste, is a set of utilities for
web development in Python. Paste has been described as "a framework forweb framework s" [http://reddit.com/r/programming/info/ehyf/comments/ceifh] .WSGI middleware
To understand the function of paste it is first necessary to understand WSGI middleware.
The
WSGI standard is an interface that allows applications to use python code to handle HTTP requests. Python code is passed a python representation of an HTTP request by an application, and in return passes back content which will normally eventually be rendered by a web browser. This Python code is called a WSGI application. A common use for this is when a web server serves content created by python code.There are, however, other uses: WSGI middleware is python code that receives a WSGI request and then performs logic based upon this request, before passing the request on to a WSGI application or more WSGI middleware. This is analogous the function of pipes on Unix systems. Functionality provided by WSGI middleware include authentication, logging,
url redirection , creation ofsessions , and compression.Python paste
The Python Paste package mainly provides python modules to act as middleware. In addition to middleware, it provides a simple python webserver that can produce WSGI request and a wrapper used to pass WSGI requests to
CGI applications. Paste may be understood as a set of libraries making use of the WSGI standard to provide functionality other than the direct creation of content. This is useful when one is deploying applications written in a python web framework.Uses of Paste
Paste is a component used in the Pylons web application framework.
