'''Python Paste''', often simply called '''paste''', is a set of [[utility software|utilities]] for [[web development]] in [[Python (programming language)|Python]]. Paste has been described as "a framework for [[web 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.

Line 10:

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 to the function of pipes on Unix systems. Functionality provided by WSGI middleware include authentication, logging, [[url redirection]], creation of [[sessions]], 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 [[Common Gateway Interface|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_Pylons (web_frameworkweb framework)|Pylons]] web application framework.
