# up.Request.prototype.headers

An object of HTTP headers that will be sent with this request.

Unpoly will by default send a number of custom request headers. See [`up.protocol`](https://unpoly.com/api/up.protocol.md) for details.

To read a single header, use [`up.Request#header()`](https://unpoly.com/api/up.Request.prototype.header.md).
