[[cgi-servlet-usage]]
==== Usage

The CGI servlet class extends the abstract HttpServlet class.
When the init parameter is called, the cgi bin directory is set with the `cgibinResourceBase`.
Otherwise, it defaults to the resource base of the context.

The cgi bin uses three parameters:

commandPrefix::
The init parameter obtained when there is a prefix set to all commands directed to the method exec.
Path::
An init parameter passed to the exec environment as a PATH.
This must be run unpacked somewhere in the filesystem.
ENV_::
An init parameter that points to an environment variable with the name stripped of the leading ENV_ and using the init parameter value.
