 * `hawk` - Options for [Hawk signing](https://github.com/hueniverse/hawk). The `credentials` key must contain the necessary signing info, [see hawk docs for details](https://github.com/hueniverse/hawk#usage-example).
 * `strictSSL` - If `true`, requires SSL certificates be valid. **Note:** to use your own certificate authority, you need to specify an agent that was created with that CA as an option.
 * `agentOptions` - Object containing user agent options. See documentation above. **Note:** [see tls API doc for TLS/SSL options](http://nodejs.org/api/tls.html#tls_tls_connect_options_callback).

+* `time` - If `true`, the request-response cycle (including all redirects) is timed at millisecond resolution, and the result provided on the response's `elapsedTime` property.
 * `jar` - If `true` and `tough-cookie` is installed, remember cookies for future use (or define your custom cookie jar; see examples section)
 * `aws` - `object` containing AWS signing information. Should have the properties `key`, `secret`. Also requires the property `bucket`, unless you’re specifying your `bucket` as part of the path, or the request doesn’t use a bucket (i.e. GET Services)
 * `httpSignature` - Options for the [HTTP Signature Scheme](https://github.com/joyent/node-http-signature/blob/master/http_signing.md) using [Joyent's library](https://github.com/joyent/node-http-signature). The `keyId` and `key` properties must be specified. See the docs for other options.
