我们有一个Kubernetes集群，其中运行了一些财务软件- Strands。当我们尝试访问前端的某个页面时，来自前端的请求将被发送到Kubernetes pod，该pod将处理该请求。
Pod运行Tomcat，我们看到请求被拒绝，并显示以下消息：

2022-10-31T10:30:46,133 INFO [UserSessionFilter.java:153] : URI :/bfm-web/config/get.action
2022-10-31T10:30:46,133 INFO [UserSessionFilter.java:154] : Remote Host :10.240.0.103

2022-10-31T10:30:54,295 INFO [UserSessionFilter.java:152] : Request not allowed. Just return a 403 status
2022-10-31T10:30:54,296 INFO [UserSessionFilter.java:153] : URI :/bfm-web/config/get.action

我不熟悉Tomcat或Java，也不知道该去哪里找。我试着检查web.xml文件中的一些过滤器，但可以找到任何线索。这是否与Kubernetes的一些授权设置有关？
让我知道什么信息，我可以与您分享，以帮助，这里有一些其他的日志，也后端使用PostgreSQL数据库的用户数据，但它似乎工作得很好：

2022-10-27T11:16:20,751 INFO  [{omitted_due_to_sec_reasons}HttpHeaderUserSessionFilter.java:71] : The header name [user.header.name] has been set to HTTP_STRANDS_USER

上面的这个对我来说很有趣，因为它似乎是一个自定义的过滤器，它设置过滤器接受特定的标题（我故意省略了一些公司信息）。有人知道我在哪里可以找到这些过滤器吗？
