"Match Ip to Session" is a security setting which, when enabled,
requires that the session ID used to access
the administration matches the operators IP address
used when logging into the admin. This is to prevent
users who follow referer links clicked on in the "data" tab that have the session ID in
the query string from gaining access to the admin. However,
the downside in enabling this is that operators with dynamic
ip addresses will not be able to log in.
"Use PHP Sessions" when enabled has Crafty Syntax use PHP sessions for the operator logging
in rather then just using cookies.
