各种条件下的301重定向

第一、ASP下得301重定向代码

%@ Language=VBScript %

%

Response.Status=301 Moved Permanently

Response.AddHeader Location, http://主域名/

%

 

第二、ASP.Net下得301重定向代码

script runat=server

private void Page_Load(object sender, System.EventArgs e)

{

Response.Status = 301 Moved Permanently;

Response.AddHeader(Location,http://主域名/);

}

/script

 

第三、PHP下得301重定向代码

header(HTTP/1.1 301 Moved Permanently);

header(Location: http://主域名/);

exit();

 

第四、CGI Perl下得301重定向代码

$q = new CGI;

print $q-redirect(http://主域名/);

 

第五、JSP下得301重定向代码

%

response.setStatus(301);

response.setHeader( Location, http://主域名/ );

response.setHeader( Connection, close );

%

 

第六、Apache下301重定向代码

新建.htaccess文件、输进下列内容(需要开启mod_rewrite):

1)将不带WWW得域名转向到带WWW得域名下

Options +FollowSymLinks

RewriteEngine on

RewriteCond %{HTTP_HOST} ^域名 [NC]

RewriteRule ^(.*)$ http://主域名/$1 [L,R=301]

 如:

#301重定向begin
Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^hnjcw.com [NC]
RewriteRule ^(.*)$ http://www.hnjcw.com/$1 [L,R=301]
#301重定向end

2)重定向到新域名

Options +FollowSymLinks

RewriteEngine on

RewriteRule ^(.*)$ http://主域名/$1 [L,R=301]

 

第七、Apache下vhosts.conf中配置301重定向

为实现URL规范化、SEO通常将不带WWW得域名转向到带WWW域名、vhosts.conf中配置为:

VirtualHost *:80

ServerName :

DocumentRoot /home/lesishu

/VirtualHost

VirtualHost *:80

ServerName lesishu.cn

RedirectMatch permanent ^/(.*) http://主域名/$1

/VirtualHost
