      Specified by:
      getServletPath in interface HttpServletRequest
      Returns:
      a String containing the name or path of the servlet being called, as specified in the request URL, decoded, or an empty string if the servlet used to process the request is matched using the "/*" pattern.

Attributes can also be set programmatically using ServletRequest.setAttribute(java.lang.String, java.lang.Object). This allows information to be embedded into a request before a RequestDispatcher call.

      Attribute names should follow the same conventions as package names. Names beginning with java.* and javax.* are reserved for use by the Servlet specification. Names beginning with sun.*, com.sun.*, oracle.* and com.oracle.*) are reserved for use by Oracle Corporation.
