Editing Web Server Gateway Interface (section)

==Background==
In 2003, Python [[web framework]]s were typically written against only [[Common Gateway Interface|CGI]], [[FastCGI]], [[mod_python]], or some other custom [[Application programming interface|API]] of a specific [[web server]].<ref>{{cite web|url=https://www.python.org/cgi-bin/moinmoin/WebProgramming|title=FrontPage - Python Wiki|website=Python.org|access-date=2017-01-27}}</ref> To quote PEP 333:

<blockquote>Python currently boasts a wide variety of web application frameworks, such as Zope, Quixote, Webware, SkunkWeb, PSO, and Twisted Web -- to name just a few. This wide variety of choices can be a problem for new Python users, because generally speaking, their choice of web framework will limit their choice of usable web servers, and vice versa... By contrast, although Java has just as many web application frameworks available, Java's "servlet" API makes it possible for applications written with any Java web application framework to run in any web server that supports the servlet API.</blockquote>

WSGI was thus created as an implementation-neutral [[interface (computer science)|interface]] between web servers and web applications or frameworks to promote common ground for [[software portability|portable]] web application development.<ref name=":0" />
