我迁移我的web应用程序从Tomcat 5.5到Tomcat 6（.0.32）。在该应用程序有每尾页ajax调用，以避免会话超时。它工作正常，在Tomcat 5.5，但它并没有在Tomcat中6工作，我使用过滤器来跟踪在数据库表中的每个电话。在非Ajax调用，我可以看到在跟踪表和复位会话超时。在Ajax调用，我可以看到跟踪表中，但不是会话超时的复位。

I migrated my webapp from Tomcat 5.5 to Tomcat 6(.0.32). In that app there are ajax calls in every footer page to avoid session timeout. It works fine on Tomcat 5.5 but it doesn't work in Tomcat 6.

On ajax calls I can see the tracking in the table but not the reset of the session timeout.

为什么呢？我可以改变这种行为？而且，只为信息，怎么能分辨的tomcat6 Ajax调用？

Why? Can I change this behavior? And, just for info, how can Tomcat6 distinguish the ajax calls?
