apache日志报错PHPNoticeUndefinedindexHTTPHOS

技术贴啊。。。

估计你是设置了负载均衡或者WAF或者设置了其他前端，总之，APACHE不是直接接收HTTP请求，然后前端转发请求给APACHE时没有带HTTP_HOST这个值，然后在程序里引用$_SERVER['HTTP_HOST']时就报错了。

最好说下你现在使用的环境，是什么在处理前端请求，才好给你建议。

谢谢！

是用了负载均衡出现这个错误的。

服务器环境win2003 Apache/2.2.25 (Win32)  PHP/5.3.5
.......

新建一个test.php，写入下面的内容
<?php
echo '<pre>';
print_r('$_SERVER');
echo '</pre>';

访问后把内容帖出来。

另外SLB里可以设置TCP和HTTP协议，不知道你现在用的是哪个，更换下试试。

-------------------------

有点错误，重试下。

<?php

echo '<pre>';
print_r($_SERVER);
echo '</pre>';

-------------------------

帖子有敏感信息，删除了。测试程序里有HTTP_HOST，但是论坛里没有，很奇怪。

http://www.discuz.net/thread-3501170-1-1.html 这个应该是你的dz发的帖子 这个还是等待dz来解决吧

lz别急，正在看，有结果马上回复亲~

-------------------------

lz好，和您进行了电话沟通，这是一个报警信息，不会影响您的使用，请亲放心！

没人吗
