This directory contains session specific subdirectories.
Each subdirectory contains transient data files used by
the server to store semi-permanent information about the session.

Note that some server software may not need to use these directories (they
may implement some other, say SQL based, method of storing semi-permanent
session-specific data).

Note that, in contrast to an instrument's PINFO directory, files in these 
subdirectories are not meant to be directly read by participants.
Instead, the server uses these files when server side scripts are executed.

Thus, this directory need NOT be web accessible.
