下面简单说在网页当中如何设置 301重定向！

1 asp程序:

dim Url: Url=request.ServerVariables("HTTP_HOST")

if Url="ywlcm.net" then

Response.Status="301 Moved Permanently"

Response.AddHeader "Location","http://www.yswlcm.net"

Response.End

end if

%>

if request.ServerVariables("HTTP_HOST")<>"http://www.yswlcm.net" then

Response.Status="301 Moved Permanently"

Response.AddHeader "Location","http://www.yswlcm.net"

Response.End

end if

%>

2 PHP程序:

$hostdomain=$_SERVER['HTTP_HOST'];

if ($hostdomain != 'www.yswlcm.net') {

header("HTTP/1.1 301 Moved Permanently");

header("location:http://www.yswlcm.net");

exit();

}

?>

3 伪静态 301代码！~

加在 index.php中的

php 后面

$jump301=1;

if(substr($_SERVER['SERVER_NAME'],0,4)!='www.'&&$jump301)

{

header('HTTP/1.1 301 Moved Permanently');

header('Location:http://www.'.$_SERVER['SERVER_NAME']);

exit();

}

4 js跳转代码

if (document.domain !='www.yswlcm.net')

this.location = "http://www.yswlcm.net" + this.location.pathname + this.location.search;
