curl通过vip+haproxy获取对象信息时，对象信息无法返回

bj我心飞翔

系统采用了vip+haproxy的方式部署。使用vip获取对象内容，对象信息过滤，使用集群的某一个节点ip则可以获取到信息。具体如下：
1、通过VIP查询容器对象信息时，对象信息被过滤。
curl -i -X HEAD http://10.0.1.156:9090/object/yu4@qq.com/yu2/swift/a.ova  -H "X_Auth_Token:gAAAAABZgoGmzxtBcMfr2zSdY66gkfctqQREdqpiv1RsmjfThuo7icBrNP5hTHdwo2vHAXhl48ZYRFP9jiCsMklbz9BipV3wA7bo7oSJMFQvINlmUHhiOjy2DRAUrwtUxCem8IQcDo5hk1GePES1oe33VvysGPPyXw"

HTTP/1.1 200 OK

2、通过网关节点IP查询容器对象信息时，返回对象信息。
curl -i -X HEAD http://10.0.1.177:9090/object/yu4@qq.com/yu2/swift/a.ova  -H "X_Auth_Token:gAAAAABZgoGmzxtBcMfr2zSdY66gkfctqQREdqpiv1RsmjfThuo7icBrNP5hTHdwo2vHAXhl48ZYRFP9jiCsMklbz9BipV3wA7bo7oSJMFQvINlmUHhiOjy2DRAUrwtUxCem8IQcDo5hk1GePES1oe33VvysGPPyXw"

这个问题应该怎么处理？？？
