HTTP status code 301 indicates permanent redirection. When the server receives a request from a client, it redirects it to another URL instead of returning the requested resource. This redirect is permanent, meaning the client should remember the new URL and use it directly on future requests.

301 status code is usually used in the following situations:

1. Website URL change: When the URL structure of the website changes or the website is migrated to a new domain name, the 301 status code can be used to change the old domain name. The URL is redirected to the new URL. This way, search engines and users can find and visit the new URL.

2. Duplicate content: When there is duplicate content on the website, you can use the 301 status code to redirect all duplicate URLs to one main URL. This helps search engines determine which URL is primary and avoids the impact of duplicate content on search rankings.

3. Old page redirection: When a page on the website no longer exists, you can use the 301 status code to redirect the URL of the page to an existing page. In this way, users who visit the old URL will be automatically redirected to the new page.

4. Redirection between HTTP and HTTPS: When a website migrates from HTTP protocol to HTTPS protocol, the 301 status code can be used to redirect the HTTP URL to the corresponding HTTPS URL. This ensures that users use a secure HTTPS connection when accessing the website.

The advantage of using the 301 status code is that it can help search engines and users quickly find and access the correct URL. Search engines will treat the redirected page as part of the target page and pass its ranking and authority to the new URL. When users access the old URL, they will be automatically redirected to the new URL, providing a better user experience.

In short, HTTP status code 301 represents a permanent redirect, which is used to redirect the requested URL to a new URL. It is commonly used in situations such as website URL changes, duplicate content, old page redirects, and redirects between HTTP and HTTPS. It can help search engines and users quickly find and access the correct URL, providing better user experience and search rankings.
