           Summary: [Chameleon-Widget]KeepSessionAlive creates invalid
                    session
           Product: Chameleon
           Version: 2.4
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Widget
        AssignedTo: chameleon-dev at lists.maptools.org
        ReportedBy: nsavard at mapgears.com


There are several instances of the following warning, I did 4-5 spotchecks and
in all cases they were calls to KeepSessionAlive.php pointing to a session dir
with a zero-size "session_file":

[06-Jun-2007 13:22:02] PHP Warning:  fread() [<a
href='function.fread'>function.fread</a>]: Length parameter must be greater
than 0 in
/path/to/htdocs/common/session/session.php on line
191

I did a test calling KeepSessionAlive.php with an invalid session ID and it
returns the message "Your session is invalid or has expired." in the browser,
but it also creates a dummy session with a zero-size file. That might explain
how those empty sessions end up there. They might be old sessions that have
expired and have been recreated by KeepSessionAlive.php. This needs to be fixed
in Chameleon.
