2. 你真正热爱的事情是什么？

所以要给自己留条翻过强（不是错别字）的梯子，翻出以前留在电脑中车仑子的工具，不得不感叹祖国的科技水平，都不能用了。

无奈google中找到了vpn这一条途径，第一感觉要找个免费的用下，可现在网上这类免费的资源少之又少。最后在yegle.net里找到了一个月只要￥20的vpn。

终于又体验到了网络的自由。

<?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past
?>

Note: You may find that your pages aren't cached even if you don't output all of the headers above. There are a number of options that users may be able to set for their browser that change its default caching behavior. By sending the headers above, you should override any settings that may otherwise cause the output of your script to be cached.

Additionally, session_cache_limiter() and the session.cache_limiter configuration setting can be used to automatically generate the correct caching-related headers when sessions are being used.

与它等效的ASP：

<pre lang="c" line="1">
#include<stdio.h>
int main(void)
{
  return 0;
}
</pre>

显示如下：

#include<stdio.h>
int main(void)
{
  return 0;
}

<pre lang="c" line="1">中的lang表示你的代码显示风格：C、HTML、ruby等等；line="1"表示显示行号，line="0"则不显示。

如果代码中包含转义字符串，要确显示字符，就要加上escaped="true"这个参数。

如输入以下代码：
<pre lang="xml" escaped="true">
&lt;xml&gt;Hello&lt;/xml&gt;
</pre>

显示结果为：

<xml>Hello</xml>
