# Supported URL components in Bulk Redirects

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/rules/url-forwarding/bulk-redirects/reference/url-components/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

The source and target URLs of a URL redirect support different URL components.

The provided URL component examples in the reference table are based on the following URL:

```txt
https://user:password@www.example.com:443/search?q=term#results
```

| **Path**For example:/search                   | Yes                                             | Yes                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               |
| **Query string**For example:q=term            | No                                              | Yes, if [**Preserve query string**](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/rules/url-forwarding/bulk-redirects/reference/parameters/#preserve-query-string) is false (optional)You can only add a query string to the target URL if you do not keep the original query string (that is, if **Preserve query string** is false). If you set **Preserve query string** to true, the query string of the request will be passed along [when there is a match for the source URL](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/rules/url-forwarding/bulk-redirects/how-it-works/#matching-the-source-url-of-redirects). |
| **Fragment**For example:results               | No                                              | Yes (optional)                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    |

Bulk Redirects also support target URLs without an authority component [2](#user-content-fn-2), like the following URL:

```txt
magnet:?xt=urn:btih:2bd9d334e8d1e5bd7768755173222db5c6dea13b&dn=archlinux-2021.07.01-x86_64.iso
```

## Footnotes

1. **Supported in source URL** \= **No** means that you cannot include the component in the source URL to match against the URL of incoming requests. [↩](#user-content-fnref-1)
2. The URL authority is the combination of user information, host, and port components. [↩](#user-content-fnref-2)
