301的具体设置方式:
1、IIS下301设置
Internet信息服务管理器 -> 虚拟目录 -> 重定向到URL,输入需要转向的目标URL,并选择“资源的永久重定向”。
2、ASP下的301转向代码
<%@ Language=VBScript %>
<%
if request.ServerVariables("SERVER_NAME")="bbs.first08.com" or request.ServerVariables("SERVER_NAME")="first08.com" then
Response.Status="301 Moved Permanently"
Response.AddHeader "Location", "http://www.first08.com/"
Response.End
end if
%>
3、ASP.Net下的301转向代码
<script runat=”server”>
private void Page_Load(object sender, System.EventArgs e)
{
Response.Status = “301 Moved Permanently”;
Response.AddHeader(”Location”,”www.first08.com/301/“);
}
</script>
4、PHP下的301转向代码
if(($HTTP_SERVER_VARS["HTTP_HOST"]=="bbs.first08.com")||($HTTP_SERVER_VARS["HTTP_HOST"]=="first08.com"))
{
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.first08.com/");
}
5、CGI Perl下的301转向代码
$q = new CGI;
print $q->redirect(”www.first08.com/301/”);
6、JSP下的301转向代码
<%
response.setStatus(301);
response.setHeader( “Location”, “www.first08.com/301/ );
response.setHeader( “Connection”, “close” );
%>
7、Apache下301转向代码
新建.htaccess文件,输入下列内容(需要开启mod_rewrite):
1)将不带WWW的域名转向到带WWW的域名下
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^lesishu.cn [NC]
RewriteRule ^(.*)$www.first08.com/301/[L,R=301]
2)重定向到新域名
Options +FollowSymLinks
RewriteEngine on
RewriteRule ^(.*)$www.first08.com/301/ [L,R=301]
3)使用正则进行301转向,实现伪静态
Options +FollowSymLinks
RewriteEngine on
RewriteRule ^news-(.+)\.html$ news.php?id=$1
将news.php?id=123这样的地址转向到news-123.html
8、Apache下vhosts.conf中配置301转向
为实现URL规范化,SEO通常将不带WWW的域名转向到带WWW域名,vhosts.conf中配置为:
<VirtualHost *:80>
ServerName www.first08.com/
DocumentRoot /home/first08
</VirtualHost>
<VirtualHost *:80>
ServerName first08.com
RedirectMatch permanent ^/(.*) www.first08.com/301/
</VirtualHost>
