window server 2003 下apache2.2.11和tomcat6.x群集时，负载平衡能成功，但是session不能复制
为方便大家参照和查找错误，所以我把配置的大部分代码都提供出来了。希望大家能够多多指点，在不同的配置文件之间我用"======================================"这样的符号隔开了。方便大家查找。
下面是Apache 2.2.11的httpd.conf的配置
httpd.conf:配置如下：

#
# Virtual Hosts
#
# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at
# <URL:http://httpd.apache.org/docs/2.2/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.
#
# Use name-based virtual hosting.
#

# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.

现在测试session是否在tomcat之间复制时,tomcat没有报错,但是session任然没有复制上
希望大家能帮我找找问题。。谢谢
