# werkzeug.routing.exceptions.RequestRedirect: 308 Permanent Redirect

- **ID:** `python/flask-werkzeug-proxy-fix`
- **Domain:** python
- **Category:** network_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

A request hits a route without the trailing slash while the route is defined with one; Werkzeug redirects and the client does not follow.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.x | active | — | — |

## Workarounds

1. **** (90% success)
   ```
   requests.get(url, allow_redirects=True)
   ```
2. **** (92% success)
   ```
   url_for('items')  # emits trailing slash if route defines it
   ```

## Dead Ends

- **** — Solves only one form; canonical URL ambiguity remains. (75% fail)
- **** — The redirect is a Werkzeug routing exception, not an app error. (85% fail)
