+The adapter will also cache the logs (if debug enabled) and even the work tables. For performance, it is best to keep debug mode off.
+
+### Verbose Mode
+
+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. Verbose mode can also be enabled/disabled by `startComputeJob` method.
+
+### Session Manager
+
+To execute a script on Viya a session has to be created first which is time-consuming (~15sec). That is why a Session Manager has been created which is implementing the following logic:
+
+1. When the first session is requested, we also create one more session (hot session) for future requests. Please notice two pending POST requests to create a session within the same context: ![the first session request](./screenshots/session-manager-first-request.png)
+2. When a subsequent request for a session is received and there is a hot session available (not expired), this session is returned and an asynchronous request to create another hot session is sent. Please notice that there is a pending POST request to create a new session while a job has been already finished execution (POST request with status 201): ![subsequent session request](./screenshots/subsequent-session-request.png)
+3. When a subsequent request for a session is received and there is no available hot session, 2 requests are sent asynchronously to create a session. The first created session will be returned and another session will be reserved for future requests.

 * `debug` - if `true` then SAS Logs and extra debug information is returned.

 * `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.

+   *
+   * @param sasJob - the path to the SAS program (ultimately resolves to
+   *  the SAS `_program` parameter to run a Job Definition or SAS 9 Stored
+   *  Process). Is prepended at runtime with the value of `appLoc`.
+   * @param data - a JSON object containing one or more tables to be sent to
+   * SAS.  For an example of the table structure, see the project README. This
+   * value can be `null` if no inputs are required.
+   * @param config - provide any changes to the config here, for instance to
+   * enable/disable `debug`. Any change provided will override the global config,
+   * for that particular function call.
+   * @param loginRequiredCallback - a function that is called if the
+   * user is not logged in (eg to display a login form). The request will be
+   * resubmitted after successful login.
+   * When using a `loginRequiredCallback`, the call to the request will look, for example, like so:
+   * `await request(sasJobPath, data, config, () => setIsLoggedIn(false))`
+   * If you are not passing in any data and configuration, it will look like so:
+   * `await request(sasJobPath, {}, {}, () => setIsLoggedIn(false))`
+   * @param extraResponseAttributes - a array of predefined values that are used
+   * to provide extra attributes (same names as those values) to be added in response
+   * Supported values are declared in ExtraResponseAttributes type.
