If you re inside a front contoller servlet which is mapped on a prefix pattern such as  foo    then you can just use HttpServletRequest getPathInfo    String pathInfo   request getPathInfo            Assuming that the servlet in your example is mapped on  secure    then this will return  users which would be the information of sole interest inside a typical front controller servlet  If the servlet is however mapped on a suffix pattern such as   foo  your URL examples however does not indicate that this is the case   or when you re actually inside a filter  when the to-be-invoked servlet is not necessarily determined yet  so getPathInfo   could return null   then your best bet is to substring the request URI yourself based on the context path s length using the usual String method  HttpServletRequest request    HttpServletRequest  req  String path   request getRequestURI   substring request getContextPath   length
