  Some headers, such as `Accept-Language` can be sent by clients as several headers each with a different value rather than sending the header as a comma separated list.

  WARNING, this can't happen with Jigsaw, all multiple values are grouped in one, and only one, header. So, this method always return ONE header value.

  If the request did not include any headers of the specified name, this method returns an empty `Enumeration`. The header name is case insensitive. You can use this method with any request header.

  Specified by:
    getHeaders in interface javax.servlet.http.HttpServletRequest
  Parameters:
    `name` - a `String` specifying the header name
  Returns:
    a `Enumeration` containing the values of the requested header, or `null` if the request does not have any headers of that name

  Specified by:
    getRequestURI in interface javax.servlet.http.HttpServletRequest

### getRequestDispatcher

    public javax.servlet.RequestDispatcher getRequestDispatcher(java.lang.String path)

  Returns a `RequestDispatcher` object that acts as a wrapper for the resource located at the given path. A `RequestDispatcher` object can be used to forward a request to the resource or to include the resource in a response. The resource can be dynamic or static.

  The pathname specified may be relative, although it cannot extend outside the current servlet context. If the path begins with a "/" it is interpreted as relative to the current context root. This method returns `null` if the servlet container cannot return a `RequestDispatcher`.

  The difference between this method and `ServletContext.getRequestDispatcher(java.lang.String)` is that this method can take a relative path.

  Parameters:
    `path` - a `String` specifying the pathname to the resource

    a `RequestDispatcher` object that acts as a wrapper for the resource at the specified path
