Gzip Expires resin

web开发中可以通过gzip压缩页面来降低网站的流量，而gzip并不会对cpu造成大量的占用. resin中配置Gzip只需要在resin配置文件中加入一个filter即可,以下测试在resin-4.0.23非专业版上进行

1.在resin.xml中<web-app ...>下增加

<web-app xmlns="http://caucho.com/ns/resin">
  <filter filter-name="gzip" filter-class="com.caucho.filters.GzipFilter">
   <init>
     <use-vary>true</use-vary>
   </init>
  </filter>

  <filter-mapping filter-name="gzip">
    <url-pattern>
      <exclude-pattern>*.png</exclude-pattern>
      <include-pattern>/*</include-pattern>
    </url-pattern>
  </filter-mapping>
</web-app>

*有些文章说此方法只对于专业版本的resin有效,但经测试非专业版也适用
