如何控制URL格式？

Question

我的web.config文件需要帮助

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
    <httpErrors errorMode="Custom">
            <remove statusCode="404"/>
            <error statusCode="404" path="/404.html" responseMode="ExecuteURL"/>
            <remove statusCode="500"/>
            <error statusCode="500" path="/index.cfm" responseMode="ExecuteURL"/>
    </httpErrors>
    </system.webServer>
</configuration>

的.htaccess

# Helicon ISAPI_Rewrite configuration file
# Version 3.0.0.29

RewriteEngine On
RewriteCompatibility2 On
RepeatLimit 200
RewriteBase 
# unsupported directive: [ISAPI_Rewrite]

RewriteCond %{HTTP:Host} ^example\.com$
RewriteRule (.*) http\://www.example.com$1 [NC,R=301,U]
RewriteRule ^/index.cfm$ http\://www.example.com [NC,R=301,U]
RewriteRule ^//index.cfm$ http\://www.example.com [NC,R=301,U]

同时拥有web.config和.htaccess

我的网站正在打开网址格式.. www。和非www以及www.example.com/index.cfm

想要以标准格式http://www.example.com

打开我的网站
