每个浏览器请求多次执行 php 脚本

Question

我在 apache 中有一个虚拟主机。我在 ubuntu 10.04 上使用 LAMP。

<VirtualHost *:80>
DocumentRoot /home/username/websites/site_folder
ServerName www.site_folder.com
ServerAlias site_folder.com
    <Directory /home/username/websites/site_folder/>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
    </Directory>
</VirtualHost>

我在/etc/hosts 中添加了这一行:

127.0.0.1 site_folder.com

在虚拟主机的文件夹中，我添加了一个名为 one.php 的 php 脚本，代码如下:

<?php
$today = getdate();
$handle = fopen("logs/logs.txt", "a");
fwrite($handle, $today['mday'].'/'.$today['mon'].'/'.$today['year']." this is a log post"." \n");
fclose($handle);
?>

当我从浏览器运行脚本时，http://localhost/one.php或 site_folder.com/one.php，logs.txt 已记录相同的消息 3 次:

12/4/2011 this is a log post 
12/4/2011 this is a log post 
12/4/2011 this is a log post 

使用 netbeans 调试器，我看到脚本实际上重复了 3 次(到达脚本末尾后，它从同一脚本的开头继续 ->one.php) 文件夹中不存在 .htaccess。

我注意到 $_SERVER['REQUEST_URI'] 每次执行/重复都会发生一些变化:

1)$_SERVER['REQUEST_URI'] => /one.php?XDEBUG_SESSION_START=netbeans-xdebug
2)$_SERVER['REQUEST_URI'] => /one.php
3)$_SERVER['REQUEST_URI'] => /one.php

我只需要记录一次消息。

我从 apache2.conf 添加了未注释的指令:

我想您已经尝试过了，但是...，您是否尝试过从真实的服务器而不是本地主机上进行操作？我的意思是，问题可能出在你的 Apache 服务器上......

我不知道，只是把它当作一个简单的想法来测试。
