+#### Pattern Syntax
+
+| Pattern | Description |
+|---------|-------------|
+| `?` | Matches exactly one character (except `/`) |
+| `*` | Matches zero or more characters that don't cross `/` |
+| `**` | Matches zero or more characters including `/` |
+
+#### Pattern Examples
+
+| Pattern | Matches | Does Not Match |
+|---------|---------|----------------|
+| `http://*.example.com` | `http://api.example.com`<br/>`http://app.example.com`<br/>`http://api.app.example.com` | `https://api.example.com`<br/>`http://example.com` |
+| `https://**.example.com` | `https://api.example.com`<br/>`https://api.app.example.com` | `http://api.example.com` |

+<Callout type="info">
+**Notes**
+
+- For `http://` and `https://` URLs, patterns match the full origin. Paths and query strings are ignored.
+- For custom schemes (like `exp://` or `myapp://`), patterns match against the full URL including paths when wildcards are present, or use prefix matching when no wildcards exist.
+- The separator is `/` (forward slash). This means `http://*.example.com` matches both `http://api.example.com` and `http://api.app.example.com`.
