actionServlet can assign multiple config files, separate by comma:

      <param-name>config</param-name>
      <param-value>/WEB-INF/struts-config.xml,/WEB-INF/struts-config1.xml,</param-value>
    </init-param>

In Struts1, Each Action is a Servlet, and each Servlet is singleton

Action scope: Default is session

• request: request.setAttribute("UserForm",userForm); //auto runs by Struts1
• session: request.getSession().setAttribute("UserForm",userForm); //auto runs by Struts1
