# Custom Headers

Custom HTTP headers are useful when you want to provide additional information to your request. If your request requires passing custom HTTP headers, all you have to do is to append `WSA-` to your header's name and add them to your request.

### Web Stealth Proxy Custom Headers Examples

```
