Summary of HTTP access 301 redirect settings in apache

1. Redirect to

Open the. htaccess file and add the following rules.

The code is as follows: Copy code

RewriteEngine On
RewriteCond % {HTTP_HOST }! ^ $ [NC]
RewriteRule ^ (. *) $ [L, R = 301]

2. Redirect to

The code is as follows: Copy code

RewriteEngine On
RewriteCond % {HTTP_HOST }! $ [NC]
RewriteRule ^ (. *) $ [L, R = 301]

To redirect a domain name without www to a domain name with www, you only need to replace the corresponding domain name with your own. If I want to jump a domain name with www to a domain name without www, I feel that it is not as simple as changing the location of two domain names, but it can be associated with the code in front of the domain name (as of % and ^) try changing the order

3. Redirect to

The code is as follows: Copy code

RewriteCond % {HTTP_HOST} ^ $
RewriteRule ^ file/file. php $ [R = 301, L]

The above code is to jump to directories and files. If your apache does not support htaccess files, we can directly set them in apache.

Use mod_rewrite to rewrite the URL

The code is as follows: Copy code
Options + FollowSymLinks
RewriteEngine on
RewriteCond % {HTTP_HOST} ^
RewriteRule ^ (. *) $ [R = permanent, L]

For more details, see:

If you do not have the apache permission, you can implement it in php code.

The code is as follows: Copy code

@ Header ("http/1.1 404 not found ");
@ Header ("status: 404 not found ");
Include ("404.html"); // jump to a page. This method is recommended.

404.html file is an error prompt file
