# Page.setExtraHTTPHeaders() method

The extra HTTP headers will be sent with every request the page initiates.

:::tip

All HTTP header names are lowercased. (HTTP headers are case-insensitive, so this shouldn’t impact your server code.)

:::

:::note

page.setExtraHTTPHeaders does not guarantee the order of headers in the outgoing requests.

#### Signature:
