Class application

Adds a processor to the application.

>>> urls = ("/(.*)", "echo")
>>> app = application(urls, globals())
>>> class echo:
...     def GET(self, name): return name
...
>>>
>>> def hello(handler): return "hello, " +  handler()
...
>>> app.add_processor(hello)
>>> app.request("/web.py").data
'hello, web.py'

Return a CGI handler. This is mostly useful with Google App Engine.
There you can just do:

    main = app.cgirun()

Makes request to this application for the specified path and method. Response will be a storage object with data, status and headers.

>>> urls = ("/hello", "hello")
>>> app = application(urls, globals())
>>> class hello:
...     def GET(self): 
...         web.header('Content-Type', 'text/plain')
...         return "hello"
...
>>> response = app.request("/hello")
>>> response.data
'hello'
>>> response.status
'200 OK'
>>> response.headers['Content-Type']
'text/plain'

To use https, use https=True.

>>> urls = ("/redirect", "redirect")
>>> app = application(urls, globals())
>>> class redirect:
...     def GET(self): raise web.seeother("/foo")
...
>>> response = app.request("/redirect")
>>> response.headers['Location']
'http://0.0.0.0:8080/foo'
>>> response = app.request("/redirect", https=True)
>>> response.headers['Location']
'https://0.0.0.0:8080/foo'

The headers argument specifies HTTP headers as a mapping object such as a dict.

>>> urls = ('/ua', 'uaprinter')
>>> class uaprinter:
...     def GET(self):
...         return 'your user-agent is ' + web.ctx.env['HTTP_USER_AGENT']
... 
>>> app = application(urls, globals())
>>> app.request('/ua', headers = {
...      'User-Agent': 'a small jumping bean/1.0 (compatible)'
... }).data
'your user-agent is a small jumping bean/1.0 (compatible)'

Starts handling requests. If called in a CGI or FastCGI context, it will follow that protocol. If called from the command line, it will start an HTTP server on the port named in the first command line argument, or, if there is no argument, on port 8080.

`middleware` is a list of WSGI middleware which is applied to the resulting WSGI function.
