在主机控制面板-isapi筛选器中启用自定义url静态化支持

RewriteCond %{REQUEST_URI} !(photo|news|page|product|advs)/ [NC]
RewriteRule ^(.*)$ /wap/$1 [L]

RewriteCond %{HTTP_USER_AGENT} "android|blackberry|googlebot-mobile|iemobile|ipad|iphone|ipod|opera\ mobile|palmos|webos" [NC]
RewriteRule ^(.*)$ http://wap.xxx.com [L,R=302]
