session parameter的意思|示意

Pages, where the URL has a session parameter, are duplicated many times in the search engine's index for your site.

包含使用了会话参数的URL的页面，会在搜索引擎中有关您站点的索引中多次复制该页面。

The session parameter can be null, meaning that the method will create a separate anonymous session, do the work and then save the session in one method call.

session参数可以为空，这表示该方法将创建一个单独的匿名会话，请创建该会话，然后在一次方法调用中保存它。

Note that no special treatment of the SAP client ID is required since it is implicitly given by the underlying session parameter.

注意，不需要对SAP客户机id进行特殊处理，因为它是通过底层会话参数隐式地提供的。
