#  http.request.headers.values 

`http.request.headers.values` ` Array<String> ` 

The values of the headers in the HTTP request.

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

The order of header values is not guaranteed but will match [http.request.headers.names](https://developers.cloudflare.com/ruleset-engine/rules-language/fields/reference/http.request.headers.names/).

Duplicate headers are listed multiple times.

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

When the HTTP request contains too many headers, this field may not contain the values of all of the headers sent in the HTTP request. In this situation, the [http.request.headers.truncated](https://developers.cloudflare.com/ruleset-engine/rules-language/fields/reference/http.request.headers.truncated/) field will be set to `true`.

**Note**: In HTTP/2, the names of HTTP headers are always in lowercase. Recent versions of the `curl` tool [enable HTTP/2 by default](https://curl.se/docs/manpage.html#--http2) for HTTPS connections.

Example value:

```
Example 1: ["application/json"]Example 2: ["This header value is longer than 10 bytes"]
```

Example usage:

```
# Example 1: Check for specific header value.any(http.request.headers.values[*] == "application/json")
# Example 2: Match requests according to the specified operator and the length/size entered for the header value.any(len(http.request.headers.values[*])[*] gt 10)
```
