1. .Lang is the i18n standard FLAG the result of parsed client browser's Accept-Language HTTP header.
   It is be used in the i18n tr function.

2. .G access GET data from URL query string. .G is a map[string][string], .G.key key is query name in query string.

3. .P access POST form data. .P is a map[string][string], .P.key key is form field name in POST form.

4. .S access session data from the current session. .S is a map[string][string], .S.key key is query name in query string.
   Notice that this only worked after the SessionStart() in a controller is be called.

5. .C access COOKIE data. .C is a map[string][string], .C.key key is cookie field name in cookies raw string.

6. .U current URL information u:=map[string]string.

7. .H request HTTP HEADER information h:=map[string]string.

   u["HOST"] = u0.Host
   u["HOSTNAME"]=u0.Hostname()
   u["PORT"]=u0.Port()
   u["PATH"] = u0.Path
   u["FRAGMENT"] = u0.Fragment
   u["OPAQUE"] = u0.Opaque
   u["RAW_PATH"] = u0.RawPath
   u["RAW_QUERY"] = u0.RawQuery
   u["SCHEME"] = u0.Scheme
   u["USER"] = u0.User.Username()
   u["PASSWORD"],_ = u0.User.Password()
   u["URI"]=u0.RequestURI()
   u["URL"]=u0.String()
   

   TIPS: [scheme:][//[userinfo@]host][/]path[?query][#fragment]
