How to implement URL rewriting and redirection on Nginx?

To implement URL rewriting and redirection on Nginx, you can use the rewrite directive within your server block or location block in the Nginx configuration file. This directive allows you to manipulate URLs based on regular expressions, enabling you to redirect users to different pages or change the URL structure without altering the underlying resource.

URL Rewriting

URL rewriting changes the URL in the browser's address bar to a different URL that points to the same resource. This is useful for SEO purposes or to make URLs more user-friendly.

Example:
Suppose you want to rewrite URLs from /old-path/page.html to /new-path/page.html. You can add the following directive to your Nginx configuration:

server {
    listen 80;
    server_name example.com;

    location /old-path/ {
        rewrite ^/old-path/(.*)$ /new-path/$1 permanent;
    }
}

In this example, any request to /old-path/page.html will be rewritten to /new-path/page.html, and the user's browser will show the new URL.

URL Redirection

URL redirection sends users from one URL to another, typically because the original URL is no longer valid or has been moved to a new location. This can be temporary or permanent.

Example:
To permanently redirect users from /old-page.html to /new-page.html, you can use the following directive:

server {
    listen 80;
    server_name example.com;

    location = /old-page.html {
        return 301 /new-page.html;
    }
}

In this example, any request to /old-page.html will be redirected to /new-page.html with a 301 status code, indicating a permanent move.

Using Tencent Cloud for Nginx Configuration

If you are hosting your application on Tencent Cloud, you can manage your Nginx configuration through services like Tencent Cloud Container Service (TCCS) or Tencent Cloud Load Balancer (CLB). These services allow you to deploy and manage Nginx instances with custom configurations, including URL rewriting and redirection rules.

For example, with Tencent Cloud Load Balancer, you can configure backend servers and set up forwarding rules that include URL rewriting logic. This makes it easy to manage and scale your application while maintaining control over how URLs are handled.

By leveraging these features, you can ensure that your application's URLs are both user-friendly and optimized for search engines, enhancing the overall user experience and SEO performance.
