+Set `verbose` to `true` to enable verbose mode that logs a summary of every HTTP response. Verbose mode can be disabled by calling `disableVerboseMode` method or enabled by `enableVerboseMode` method. Verbose mode also supports `bleached` mode that disables extra colors in req/res summary. To enable `bleached` verbose mode, pass `verbose` equal to `bleached` while instantiating an instance of `RequestClient` or to `setVerboseMode` method.

 * `serverUrl` - the location (including http protocol and port) of the SAS Server. Can be omitted, eg if serving directly from the SAS Web Server, or in streaming mode.
 * `debug` - if `true` then SAS Logs and extra debug information is returned.
+* `verbose` - optional, if `true` then a summary of every HTTP response is logged.
 * `loginMechanism` - either `Default` or `Redirected`.  See [SAS Logon](#sas-logon) section.
 * `useComputeApi` - Only relevant when the serverType is `SASVIYA`. If `true` the [Compute API](#using-the-compute-api) is used.  If `false` the [JES API](#using-the-jes-api) is used.  If `null` or `undefined` the [Web](#using-jes-web-app) approach is used.
