<h2>Overview</h2><div class="docstring">

<div class="discussion">
|
||
|
||
<p>The purpose of the session manager is to keep track of sessions that are created during the course of a framework instance’s lifetime. When exploits succeed, the payloads they use will create a session object, where applicable, there will implement zero or more of the core supplied interfaces for interacting with that session. For instance, if the payload supports reading and writing from an executed process, the session would implement SimpleCommandShell in a method that is applicable to the way that the command interpreter is communicated with.</p>
