IIS7.5 web.config Rewrite Rules 防盗链

在web.config中加入rewrite规则

格式如下：
 

<system.webServer>
		 <security>
		  <requestFiltering allowDoubleEscaping="true"></requestFiltering>      
		</security>
        <directoryBrowse enabled="false" />
        <defaultDocument>
            <files>
                <clear />
                <add value="index.htm" />
                <add value="index.html" />
                <add value="iisstart.htm" />
            </files>
        </defaultDocument>
		<rewrite>
			<rules>
				<rule name="Forbid image">
				<match url="^.*comicdata.*.(txt|doc|gif|jpg|jpeg|png|mp3|flv|swf)$" ignoreCase="true" />
				<conditions>
				<add input="{HTTP_REFERER}" pattern="^http://(www.)?yzmanga.com/.*$" negate="true" />
				<add input="{REMOTE_ADDR}" pattern="221.232.16.*" negate="true" />
				</conditions>
				<action type="Rewrite" url="/static/image/common/logo.png" />
				</rule>
			</rules>
		</rewrite>
    </system.webServer>
