图片服务器 带宽越来越不够用，还有当一台服务器的机房出问题的时候，不影响 整个web，以及 考虑网通电信访问服务器的 速度，所以考虑使用多台 图片 服务器
这个时候要求 图片服务器 内容是同步 的
所以写了此程序，写的比较烂，还请批评指正，
也好让我有所提高
我在测试的时候通过，修改 system32/dirvers/etc/HOST 来实现 test.com 域名
web.config 中的内容如下：
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="upload1" value="http://1.test.com:81/ReqFile.aspx" /> <!--这里是第一台图片服务器-->
<add key="upload2" value="http://2.test.com:81/ReqFile.aspx" /> <!--这里是第二台图片服务器-->
<add key="upload3" value="http://3.test.com:88/upload.php" /> <!--这里是第三台图片服务器-->
<add key="imgurlprev" value="http://images.test.com:81/files/" /> <!--这个是上传后图片 生成图片的 url 前缀-->
<add key="imgserverpwd" value="930B194D9C47126CFFE430720CCADBB4" /> <!--这里在 url 中加入密文，用于解密 -->
</appSettings>
<connectionStrings/>
<system.web>
<pages enableEventValidation="false" viewStateEncryptionMode="Never" />
<compilation debug="true"/>
<authentication mode="Windows" />
</system.web>
</configuration>
