+# Wiki Redirection Implementation
+
+## Overview
+
+This document explains the implementation of the redirection from `/wiki` routes to `https://qualiwiki.cipherbliss.com/wiki`.
+
+## Implementation Details
+
+The redirection is implemented using a Symfony Event Subscriber that intercepts all requests to paths starting with `/wiki` before they reach the routing system.
+
+### Files Created
+
+- `src/EventSubscriber/WikiRedirectSubscriber.php`: Event subscriber that handles the redirection
+
+### How It Works
+
+1. The `WikiRedirectSubscriber` subscribes to the `kernel.request` event with a high priority (256)
+2. When a request is received, the subscriber checks if the path starts with `/wiki`
+3. If it does, it extracts the part after `/wiki` and constructs a redirect URL by appending this part to `https://qualiwiki.cipherbliss.com/wiki`
+4. It creates a 301 (permanent) redirect response and sets it on the event
+5. This short-circuits the request handling process, preventing the request from reaching the routing system
+
+### Example Redirects
+
+- `/wiki` → `https://qualiwiki.cipherbliss.com/wiki`
+- `/wiki/` → `https://qualiwiki.cipherbliss.com/wiki`
+- `/wiki/page1` → `https://qualiwiki.cipherbliss.com/wiki/page1`
+- `/wiki/page1/subpage` → `https://qualiwiki.cipherbliss.com/wiki/page1/subpage`
+
+### Technical Considerations
+
+- The subscriber uses a high priority (256) to ensure it runs before the router processes the request
+- It only processes main requests, not sub-requests
+- It uses a 301 (permanent) redirect status code, which is appropriate for this type of redirection
+- The implementation follows Symfony best practices for event subscribers
+- The subscriber is automatically registered thanks to Symfony's auto-configuration feature
+
+## Testing
+
+To test the redirection:
+
+1. Access any path starting with `/wiki` in the application
+2. Verify that you are redirected to the corresponding path on `https://qualiwiki.cipherbliss.com/wiki`
+3. Check that the redirect is a 301 (permanent) redirect
+
+## Maintenance
+
+If the target URL needs to be changed in the future, update the `REDIRECT_BASE_URL` constant in the `WikiRedirectSubscriber` class.
