What are Server Redirects?
In the early days of the web, when websites were hosted on shared servers, if a user requested a different version of a webpage (e.g., one with different images), they would receive an error message or be redirected to a different page. This was known as a "Server Redirect."
Why Do We Need Server Redirects?
Today, websites are hosted on dedicated servers, and requests for specific versions of content can occur due to caching issues, changes in the server's configuration, or other technical reasons. Server redirects help resolve these issues by providing a permanent redirect to a new URL.
How do Server Redirects Work?
Here's a step-by-step explanation of the process:
- A request is made to the website, which checks if there's an available version at the requested URL.
- If no available version exists, the browser will be redirected to a new URL (the redirect target).
- The redirect target can also use caching mechanisms to store copies of content from different URLs, making future requests faster.
Real-World Examples
In the example below, if a user visits /old-path, they'll be redirected to /new-path due to a server redirect.
