1. 去微软官网下载Url Reqrite Module 2.0安装 ;
2. 关闭然后再打开IIS信息服务（IIS）管理器窗口，就能够看到Url Rewrite模块了
3. 双击Url Rewrite模块，就能看到如下界面进行规格配置
规则也可以直接去web.config文件配置。
如下是我配置的一个规则：移动端访问PC端站点的时候直接跳转到移动端站点
<system.webServer><rewrite><rules><rule name="UserAgentRedirect" stopProcessing="true"><match url="^(.*)$" /><conditions><add input="{HTTP_USER_AGENT}" pattern="(iphone|android|phone|mobile|wap|netfront|java|opera mobi,opera mini|ucweb|windows ce|symbian|series|webos|sony|blackberry|dopod,nokia|samsung|palmsource|xda|pieplus|meizu|midp|cldc|motorola|foma,docomo|up.browser|up.link|blazer|helio|hosin|huawei|novarra|coolpad|webos|techfaith|palmsource|alcatel|amoi|ktouch|nexian|ericsson|philips|sagem|wellcom|bunjalloo|maui|smartphone|iemobile|spice|bird|zte-|longcos|pantech|gionee|portalmmm|jig browser|hiptop|benq|haier|^lct|320x320|240x320|176x220|w3c |acs-|alav|alca|amoi|audi|avan|benq|bird|blac|blaz|brew|cell|cldc|cmd-|dang|doco|eric|hipt|inno|ipaq|java|jigs|kddi|keji|leno|lg-c|lg-d|lg-g|lge-|maui|maxo|midp|mits|mmef|mobi|mot-|moto|mwbp|nec-|newt|noki|oper|palm|pana|pant|phil|play|port|prox|qwap|sage|sams|sany|sch-|sec-|send|seri|sgh-|shar|sie-|siem|smal|smar|sony|sph-|symb|t-mo|teli|tim-|tosh|tsm-|upg1|upsi|vk-v|voda|wap-|wapa|wapi|wapp|wapr|webc|winw|winw|xda|xda-,Googlebot-Mobile)" /></conditions><action type="Redirect" url="" /></rule></rules></rewrite></system.webServer>
4. 规则配置好后重新启动站点，配置的规则就可以生效了;
