Tomcat6支持Comet了

摘要： Comet support allows a servlet to process IO aynchronously, recieving events when data is available for reading on the connection (rather than always using a blocking read), and writing data back on connections asychnonously (most likely responding to some event raised from some other source).

比我自己的Comet实现相比，更充分利用了tomcat自身的资源，但因为不属于servlet标准，因此不具备服务器兼容性。

给点代码实例就好了.
