Alfresco GetContentChanges返回“；“未经授权”；

我通过DotCMIS+HTTPS从Alfresco 4.2.0获得如下更改：

string lastTokenOnClient = "1857698"; // actually updated using last token
boolean includeProperties = false;
int maxNumItems = 100;

session.GetContentChanges(lastTokenOnClient, includeProperties, maxNumItems);

虽然它通常可以正常工作，但有时会出现以下错误（客户端）：

此错误出现在露天侧：

我看不出对

GetContentChanges

的调用如何在几分钟内成功，但在同一会话中开始返回

Unauthorized

我做错什么了吗？

问题是使用了旧的CMIS URL

http://[host]：[port]/alfresco/cmisatom

解决方案：

---

将配置中的URL替换为新的CMIS URL

http://[host]：[port]/alfresco/api/-default-/public/CMIS/versions/1.0/atom

解决了问题。

会话是否超时？一旦更改停止，其他CMIS调用是否工作，还是也会失败？
