# Context

In LiteSpeed Web Server terminology, a "context" is a virtual location, a common parent URL, that identifies a group of resources. Contexts can be thought of as different directories in your website's directory tree. For example, "/" is the root context mapped to the document root of a website. "/cgi-bin/" is a context farther up on the tree, dedicated to the CGI applications for this site. A context can be explicitly defined in LiteSpeed's WebAdmin console for the following purposes:

- To make a file system outside of the document root accessible.
- To block access to certain resources.
- To setup user-level authentication for certain resources.
- To create mount points for external applications.
- To redirect requests to another location.
