www.mywebsite.com 与www.mywebsite.com/index.php 在搜索引擎看来是两个页面相同内容,那我们可以用永久重定向来处理这个问题。
Php代码:
Header( “HTTP/1.1 301 Moved Permanently” );
Header( “Location: http:// www.mywebsite.com” );
Jsp代码
response.setStatus(301);
response.setHeader( "Location", "http://www.mywebsite.com " );
response.setHeader( "Connection", "close" );
ASP .NET代码
<script runat=”server”>
private void Page_Load(object sender, System.EventArgs e )
{
Response.Status = “301 Moved Permanently”;
Response.AddHeader(”Location”,”http://www.mywebsite.com”);
}
</script>
如果你有修改服务器配置文件的权限,或者有提供此功能,可以使用htaccess
.htaccess
# 将网页index.php重定向到http://www.mywebsite.com
Redirect permanent /index.php http://www.mywebsite.com
