301 redirection: refers to a very important "automatic redirection" technology - actually not a technology, that is, URL redirection - when users visit an address or directory, they can specify to jump to another address.
301 redirection, this is the only redirection among all redirection methods that conforms to seo/seo.html" target="_blank">search engine rules. This is also a basic term in SEO, for example: a website uses www.bKjia. When c0m and bKjia.c0m are bound, there will be two weights. If bKjia.c0m is redirected to www.bKjia.c0m, the weights will be concentrated and the weight value will be increased accordingly
.
1. Set up 301 redirection on the IIS server
Preparation work: You must have server setting permissions and you can open a new virtual space at will!
First, create a new virtual space and bind the domain name you need to redirect to;
Second, My Computer-->Open "Control Panel"-->"Administrative Tools"-->Open "Internet Information Services", there will be a tree menu on the left, find your website--right click" Properties"--Select the "Home Directory" tab, then select "Redirect to URL", then enter the target domain name that needs to be directed in the address box, and finally select "Permanent redirection of resources" in the tab and click "OK" to complete the operation. Property interface settings, as shown below:

2. Set apache 301 redirection on the Unix/linux host

Create a new .htaccess file and enter the following content (mod_rewrite needs to be turned on):
1) Forward the domain name without WWW to the domain name with WWW

The code is as follows

Copy code

Options +FollowSymLinks

代码如下	复制代码
Options +FollowSymLinks RewriteEngine on  RewriteCond %{HTTP_HOST} ^bKjia.c0m [NC] RewriteRule ^(.*)$www.bKjia.c0m/301/[L,R=301]

RewriteEngine on RewriteCond %{HTTP_HOST} ^bKjia.c0m [NC]
RewriteRule ^(.*)$www.bKjia.c0m/301/[L,R=301]

2) Redirect to new domain name

代码如下	复制代码
Options +FollowSymLinks RewriteEngine on  RewriteRule ^(.*)$www.bKjia.c0m/301/ [L,R=301]

The code is as follows	Copy code
Options +FollowSymLinks RewriteEngine on RewriteRule ^(.*)$www.bKjia.c0m/301/ [L,R=301]

3) Use regular rules to perform 301 redirection to achieve pseudo-static

代码如下	复制代码
Options +FollowSymLinks RewriteEngine on  RewriteRule ^article-(.+).html$ article.php?id=  将article.php?id=123这样的地址转向到article-123.html

The code is as follows	Copy code

3. Set the 301 redirect code in the ASP program page
In the public header file or global call file, add the following code:

The code is as follows

代码如下	复制代码
Response.Status="301 Moved Permanently" Response.AddHeader "Location", "http://www.bKjia.c0m" Response.End  end if %>

Copy code

Response.Status="301 Moved Permanently" Response.AddHeader "Location", "http://www.bKjia.c0m" Response.End end if %>
Principle: Determine whether the requested server_name is the same as the main target URL. If not, redirect

代码如下	复制代码
$host= 'www.bKjia.c0m'; //你目标定向的网址  if ($_SERVER['HTTP_HOST'] != $host)//若不是则进行重定向，后面页面参数不变 { header("HTTP/1.1 301 Moved Permanently"); header("Location: http://{$host}{$_SERVER[REQUEST_URI]}"); } unset($host);

(more perfect way of writing)

The code is as follows

Copy code

$host= 'www.bKjia.c0m' ; //Your target URL if ($_SERVER['HTTP_HOST'] != $host)//If not, redirect will be performed, and the subsequent page parameters will remain unchanged { header("HTTP/1.1 301 Moved Permanently"); header("Location: http://{$host}{$_SERVER[REQUEST_URI]}"); } unset($host); Principle: First define the target directional URL, and then determine whether the host currently requested to access is consistent.
