# Edge Rules

> Create powerful custom behaviors for your CDN using Edge Rules to control redirects, headers, caching, and origin routing.

Edge Rules allow you to create powerful custom behaviors for your pull zone, such as redirects, header modifications, cache time overrides, or origin changes based on incoming request data.

## How to access Edge Rules

<Steps>
  <Step title="Navigate to your Pull Zone">
    Go to **CDN** in the dashboard and select the pull zone you want to
    configure.
  </Step>

  <Step title="Open Edge Rules">
    Click on the **Edge Rules** tab in the pull zone settings.
  </Step>

  <Step title="Add a new rule">
    Click **Add Edge Rule** to create a new rule with your desired action and
    trigger conditions.
  </Step>
</Steps>

## What can Edge Rules do?

Edge Rules support a variety of actions that execute at different layers of the CDN:

| Action                                  | Description                                     |
| --------------------------------------- | ----------------------------------------------- |
| **Force SSL**                           | Redirect HTTP requests to HTTPS                 |
| **Redirect to URL**                     | Redirect requests to a different URL            |
| **Change Origin URL**                   | Route requests to a different origin server     |
| **Override Cache Time**                 | Set custom cache duration for matching requests |
| **Block Request**                       | Block requests that match certain conditions    |
| **Set Response Header**                 | Add or modify response headers                  |
| **Set Request Header**                  | Add or modify headers sent to the origin        |
| **Force Download**                      | Force the browser to download the file          |
| **Disable/Enable Token Authentication** | Control token authentication per request        |
| **Override Browser Cache Time**         | Set custom browser cache duration               |
| **Set Network Rate Limit**              | Limit bandwidth for matching requests           |
| **Enable/Disable Request Coalescing**   | Control request coalescing per request          |

## Need more power?

For complex request and response transformations that go beyond what Edge Rules can offer, consider using [Middleware Scripts](/scripting/middleware/overview). Middleware scripts allow you to write custom code that executes at the edge, giving you full programmatic control over request handling, response modification, and routing logic.
