this is the gluon wsgi application. the first function called when a page
is requested (static or dynamic). it can be called by paste.httpserver
or by apache mod_wsgi.

  - fills request with info
  - the environment variables, replacing '.' with '_'
  - adds web2py path and version info
  - compensates for fcgi missing path_info and query_string
  - validates the path in url

The url path must be either:

1. for static pages:

  - /&lt;application&gt;/static/&lt;file&gt;

2. for dynamic pages:

  - /&lt;application&gt;[/&lt;controller&gt;[/&lt;function&gt;[/&lt;sub&gt;]]][.&lt;extension&gt;]
  - (sub may go several levels deep, currently 3 levels are supported:
     sub1/sub2/sub3)

The naming conventions are:

  - application, controller, function and extension may only contain
    [a-zA-Z0-9_]
  - file and sub may also contain '-', '=', '.' and '/'
