# Perform mobile redirects

Create a redirect rule to redirect visitors using mobile devices to a different hostname.

Last updated May 5, 2026|Copy as Markdown| [View as Markdown](https://developers.cloudflare.com/rules/url-forwarding/examples/perform-mobile-redirects/index.md)| [Agent setup](https://developers.cloudflare.com/agent-setup/)

The following examples will redirect visitors using mobile devices — based on the request user agent string — to a different hostname.

## Redirect mobile users dropping the original URI path

This example static redirect will redirect requests for the current zone (`example.com`) from mobile users to `m.example.com` without preserving the URI path in the original HTTP request.

**When incoming requests match**

- Enter the following expression in the [Expression Editor](https://developers.cloudflare.com/ruleset-engine/rules-language/expressions/edit-expressions/#expression-editor):  
  `not http.host in {"m.example.com"} and (http.user_agent contains "mobi" or http.user_agent contains "Mobi")`

**Then**

- **Type:** *Static*
- **URL:** `m.example.com`
- **Status code:** *301*

Notes about this example:

- The `not http.host in {"m.example.com"}` condition prevents redirect loops.
- The user agent condition follows [Mozilla's recommendation ↗︎](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/User-Agent/Firefox#device-specific_user_agent_strings) for identifying mobile devices.
- The **Then** > **URL** value should be the same as the one you entered in the `http.host` condition of the rule's filter expression.
- You can redirect users to other zones on Cloudflare or to other hostnames not on Cloudflare.

## Redirect mobile users keeping the original path

This example single redirect will redirect requests for the current zone (`example.com`) from mobile users to `m.example.com`, keeping the URI path of the original HTTP request.

**When incoming requests match**

- Enter the following expression in the [Expression Editor](https://developers.cloudflare.com/ruleset-engine/rules-language/expressions/edit-expressions/#expression-editor):  
  `not http.host in {"m.example.com"} and (http.user_agent contains "mobi" or http.user_agent contains "Mobi")`

**Then**

- **Type:** *Dynamic*
- **Expression:** `concat("https://m.example.com", http.request.uri.path)`
- **Status code:** *301*

Notes about this example:

- The `not http.host in {"m.example.com"}` condition prevents redirect loops.
- The user agent condition follows [Mozilla's recommendation ↗︎](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/User-Agent/Firefox#device-specific_user_agent_strings) for identifying mobile devices.
- The hostname in **Then** > **Expression** should be the same as the one you entered in the `http.host` condition of the rule's filter expression.
- Depending on your use case, you may want to enable **Then** > **Preserve query string** to also keep the query string of the original request.
- You can redirect users to other zones on Cloudflare or to other hostnames not on Cloudflare.
