How to Change Domain Name By .Htaccess?

To change the domain name using .htaccess, you can do the following:

1. Create a new .htaccess file in the root directory of your website.
2. Add the following code to the .htaccess file: RewriteEngine on RewriteCond %{HTTP_HOST} ^olddomain.com [NC] RewriteRule ^(.*)$ http://newdomain.com/$1 [L,R=301]
3. Replace "olddomain.com" with your current domain name and "newdomain.com" with the new domain name.
4. Save the .htaccess file and upload it to the root directory of your website.
5. Test the redirection by typing your old domain name in the browser. It should automatically redirect to the new domain name.

Please note that changing the domain name using .htaccess can impact your website's SEO, so make sure to properly set up 301 redirects to avoid any negative effects.

What is the purpose of the RewriteEngine directive in .htaccess?

The RewriteEngine directive in .htaccess is used to enable the Apache web server's mod_rewrite module, which allows for URL rewriting and redirection. This directive is used to manipulate URLs and customize the way web pages are accessed and displayed on a website. It is commonly used for creating search engine friendly URLs, redirecting old URLs to new ones, and setting up custom error pages.

What is the syntax for setting up a subdomain redirect with .htaccess?

To set up a subdomain redirect using .htaccess, you can use the following syntax:

1
2
3

RewriteEngine On
RewriteCond %{HTTP_HOST} ^subdomain\.example\.com$
RewriteRule ^(.*)$ http://www.example.com/newpage [L,R=301]

In this syntax:

• Replace "subdomain.example.com" with your subdomain.
• Replace "http://www.example.com/newpage" with the URL you want the subdomain to redirect to.
• [L] flag means this is the last rule and no other rules will be processed if this one matches.
• [R=301] flag indicates a permanent redirect.

Make sure to test the redirect after adding this code to your .htaccess file to ensure it is working correctly.

How to block access to certain file extensions using .htaccess?

To block access to certain file extensions using .htaccess, you can use the following code in your .htaccess file:

1
2
3
4

<FilesMatch "\.(php|html|htm|txt)$">
  Order allow,deny
  Deny from all
</FilesMatch>

In this code snippet, the FilesMatch directive is used to specify the file extensions that you want to block access to. You can add or remove file extensions as needed by separating them with a pipe | character within the parenthesis.

The Order allow,deny directive specifies that the Deny from all directive should take precedence over any Allow directives. This ensures that access is denied to files with the specified extensions.

After adding this code to your .htaccess file and uploading it to your server, any requests to access files with the specified extensions will be denied.
