Question

我有Apache反向代理，它是使用mod_jk连接tomcat的后端Apache的请求，应用程序在java / jsps中在Apache反向代理中，我有这样的配置，当GET请求中存在带有out参数的请求时，该配置有效：

ProxyRequests     Off
ProxyPreserveHost On
ProxyPass /users/ http://1x2.xxx.4.xx:5xxxx/jsp/app/New/
ProxyPassReverse /users/  http://1x2.xxx.4.xx:5xxxx/jsp/app/New/
CustomLog /home/Apache/logs/proxy_log common

mod_proxy日志：

1xx.1xx.3.xx - - [20/Nov/2012:14:07:54 +0200] "GET /users/ HTTP/1.1" 200 3547

每次收到回复时都可以看到：

"GET /jsp/app/New/Home.jsp?event=Validated HTTP/1.1" 404 306

失败了当我尝试在没有代理服务器的情况下直接使用它时页面正常工作。

你需要使用Apache Httpd v2.2 +并在ProxyPass配置中指定'nocanon'选项，它告诉Apache不要规范请求查询字符串：

ProxyPass /users/ http://1x2.xxx.4.xx:5xxxx/jsp/app/New/ nocanon

mod_proxy可以使用params处理GET响应（使用tomcat作为后端）
