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
