This allows you to create custom URL structures or redirect old URLs to new ones. By editing the .htaccess file in your web server's root directory, you can specify the rewrite rules and conditions to achieve the desired URL changes. Remember to test the changes thoroughly to ensure they work as expected without disrupting the functionality of your website.
What is the meaning of RewriteCond in .htaccess?
In a .htaccess file, RewriteCond is a directive used to specify one or more conditions that must be met for a RewriteRule to be applied. These conditions can include various criteria, such as HTTP headers, server variables, or file attributes. If the conditions specified in RewriteCond are met, the RewriteRule associated with those conditions will be applied to rewrite or redirect the URL as specified. Essentially, RewriteCond is used to set up conditional logic for URL rewrites or redirects in Apache's mod_rewrite module.

How to redirect non-www to www using .htaccess?
To redirect non-www to www using .htaccess, you can add the following code to your .htaccess file:
1 2 3 |
RewriteEngine On RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L] |

How to prevent image hotlinking using .htaccess?
To prevent image hotlinking using .htaccess, you can add the following code to your .htaccess file:
1 2 3 4 |
RewriteEngine on RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yourdomain.com [NC] RewriteRule \.(jpg|jpeg|png|gif)$ - [NC,F] |
Replace yourdomain.com with your actual domain name. This code will block any requests for image files (jpg, jpeg, png, gif) that are not coming from your domain. This means that if someone tries to hotlink to one of your images from another website, the image will not be displayed.
Remember to test this code on a staging site before implementing it on your live site to ensure it does not block any legitimate requests.
