#  http.request.body.form 

`http.request.body.form` ` Map<Array<String>> ` 

The HTTP request body of a form represented as a Map (or associative array).

Populated when the `Content-Type` header is `application/x-www-form-urlencoded`.

The values are not pre-processed and retain the original case used in the request.

When a field repeats, then the array contains multiple items in the order they are in the request.

The return value may be truncated if [http.request.body.truncated](https://developers.cloudflare.com/ruleset-engine/rules-language/fields/reference/http.request.body.truncated) is `true`.

* **Decoding**: No decoding performed
* **Whitespace**: Preserved
* **Non-ASCII**: Preserved

Requires a Cloudflare Enterprise plan.

Example value:

```
{username": ["admin"]}
```

Example usage:

```
any(http.request.body.form["username"][*] == "admin")
```

Warning 

All `http.request.body.*` fields (except [ http.request.body.size ](https://developers.cloudflare.com/ruleset-engine/rules-language/fields/reference/http.request.body.size/)) handle a given maximum body size, which varies per plan. For Enterprise customers, the maximum body size is 128 KB. For other paid plans, the limit is lower by default — reach out to your account team or to Cloudflare Support to increase the limit. For users in the Free plan, the limit is 1 MB. 

You cannot define expressions that rely on request body data beyond the maximum size set for your plan. If the request body is larger, the body fields will contain a truncated value and the [ http.request.body.truncated ](https://developers.cloudflare.com/ruleset-engine/rules-language/fields/reference/http.request.body.truncated/) field will be set to `true`. The [ http.request.body.size ](https://developers.cloudflare.com/ruleset-engine/rules-language/fields/reference/http.request.body.size/) field will contain the full size of the request without any truncation. 

The maximum body size applies only to the values of HTTP body fields — the origin server will still receive the complete request body.
