            如果addheader、setheader 的value值以request.parameters.开头则表示从request.parameters中获取对应的parameter值
            如果addheader、setheader 的value值以request.headers.开头则表示从request.headers中获取对应的header值
            例如下面例子是在Response输出header时添加两个header（一个addHeader， 一个setHeader）。
+           options 节点: 设置了该节点却auto=true，当request的method=OPTIONS自动设置addheader、setheader并返回200状态码
