# URL_TOO_LONG

The `URL_TOO_LONG` error occurs when the URL of the request exceeds the maximum length allowed by the CDN (**14 KB**). Long URLs can be a result of long query strings, lengthy path segments, or an excessive number of path segments.

## Troubleshoot

To troubleshoot this error, follow these steps:

1. **Shorten the URL:** Simplify the URL by reducing the length of the path segments and the query string
2. **Reduce query parameters:** If the URL has many query parameters, consider reducing the number of parameters or use `POST` method instead where the parameters can be sent in the body of the request
3. **Use POST method:** If the long URL is a result of a form submission, consider changing the form method from `GET` to `POST`
4. **Check for unintended redirection:** Ensure there isn't a redirection loop or logic that is appending to the URL causing it to grow in length with each redirect
