## Control request and response body buffering in Configuration Rules

[Rules](https://developers.cloudflare.com/rules/)

You can now control how Cloudflare buffers HTTP request and response bodies using two new settings in [Configuration Rules](https://developers.cloudflare.com/rules/configuration-rules/).

#### Request body buffering

Controls how Cloudflare buffers HTTP request bodies before forwarding them to your origin server:

| Mode | Behavior |
| --- | --- |
| **Standard** (default) | Cloudflare can inspect a prefix of the request body for enabled functionality such as WAF and Bot Management. |
| **Full** | Buffers the entire request body before sending to origin. |
| **None** | No buffering — the request body streams directly to origin without inspection. |

#### Response body buffering

Controls how Cloudflare buffers HTTP response bodies before forwarding them to the client:

| Mode | Behavior |
| --- | --- |
| **Standard** (default) | Cloudflare can inspect a prefix of the response body for enabled functionality. |
| **None** | No buffering — the response body streams directly to the client without inspection. |

Caution

Setting body buffering to **None** may break security functionality that requires body inspection, including the Web Application Firewall (WAF) and Bot Management. Ensure that any paths where you disable buffering do not require security inspection.

#### API example

```json
{
  "action": "set_config",
  "action_parameters": {
    "request_body_buffering": "standard",
    "response_body_buffering": "none"
  }
}
```
