Some browsers cannot get session value after Java project is deployed on WebLogic

Java Web project tested in local browser everything is OK, local Firefox, Chrome, ie8,360 browser version number:7.1.1.558 kernel version: 31.0.1650.63 can be used normally. After deploying to the test environment, the browser access for this machine is also all working properly. But the testers have a version of 360 browsers version number:7.1.1.556 kernel version: 31.0.1650.63 not available, with this browser version can access my local program can be used normally. However, access to the test environment is not available. The reason why the function is not available is that the test environment session does not get the value of the session before it (the session is not invalidated because the intermediate operation is coherent). But other browsers in both the native and the test environment can be taken before the value of the session saved.

The local Web container is: tomcat6
The Web container for the test server is: weblogic11g
===================================
The question now is:
1, why the same 360 browser in my local program easy to use, in the test environment is not useful?
2, why the same test environment, some browsers can be taken from the session value, some browser can not?
