    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:

      - /<application>/static/<file>

    2. for dynamic pages:

      - /<application>[/<controller>[/<function>[/<sub>]]][.<extension>]
      - (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 '/'

      - 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:

      - /<application>/static/<file>

    2. for dynamic pages:

      - /<application>[/<controller>[/<function>[/<sub>]]][.<extension>]
      - (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 '/'
