 An array of client certificates to be used. Each certificate object must have `cert` and `key` or `pfx` to load the client certificate. Optionally, `passphrase` property should be provided if the private key is encrypted. If the certificate is valid only for specific URLs, the `url` property should be provided with a glob pattern to match the URLs that the certificate is valid for.
