百分请教~ apache2.2+tomcat5出现502Proxy Error错误~
前几天网站服务器换ip，进行一番修改后能正常访问。可这两天一打开网站主页就报下面的错误：
Proxy Error
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /.
Reason: DNS lookup failure for:www.xxx.com
打开apache的error.log
看到

这样的错误，不知道到底是哪出错了~
望指教~
[解决办法]
如果很少的话那就是单纯的http代理出错,修改下配置应该可以解决
