How to redirect in nginx

The methods for redirecting through Nginx are 301 permanent redirects (update links or mobile pages) and 302 temporary redirects (handle errors or temporary changes). Configuring redirection involves using location directives in server blocks, and advanced features include regular expression matching, proxy redirection, and condition-based redirection. Common uses of redirects include updating URLs, handling errors, redirecting HTTP to HTTPS, and guiding users to a specific country or language version.

How to redirect using Nginx

Nginx is a popular web server that provides multiple ways to redirect requests. Redirection is useful for modifying the URL structure of a website, handling errors, or directing users to other pages.

Redirect method

There are two main redirect methods in Nginx:

• 301 Permanent Redirect: This redirect indicates that the browser permanently moves the URL. It is used to update outdated links or move pages to a new location.
• 302 Temporary Redirect: This redirect indicates that the browser changes temporarily to the URL. It is used to handle errors, maintain, or direct users to other pages.

Configure redirection

Use server blocks to configure redirection in Nginx configuration files. The following example demonstrates how to permanently redirect example.com/old-page to example.com/new-page :

 <code class="nginx">server { server_name example.com; location /old-page { return 301 https://example.com/new-page; } }</code>

Advanced Redirection

Nginx also provides the following advanced redirect capabilities:

• Use regular expressions: You can use regular expressions to match the requested URL and redirect it.
• Agent Redirection: Allows redirection of requests to other servers.
• Condition-based redirection: Perform redirection based on request headers, server variables, or other conditions.

Common uses

Common uses of Nginx redirection include:

• Update outdated URLs
• Handle 404 error
• Redirect HTTP requests to HTTPS
• Boot the user to a different country or language version

By leveraging Nginx's redirection capabilities, you can optimize website navigation, improve user experience, and modify website structure as needed.
