session storage

[Alex Greif <al...@greifdesign.net>]

Hi,

I am completely new to rivet and have the following question:
In the user manual I found the description how to use sessions which
stores the session data in a DB

Is there a way to store session data without a DB, say in cookies or on
the filesystem?

Thanks,
Alex.

of course a cookie management command exists
(http://tcl.apache.org/rivet/manual2.1/cookie.html).

In the first place Rivet wants to bring the Tcl command language into
the Apache webserver. So there are no restrictions or limitations as to
using filesystem I/O commands such as 'open' 'read' etc etc. Recently
Harald Oelhmann found out the Tcl notifier (hence the event loop) is not
working in a Rivet build with a threaded Tcl. A fix was proposed and
applied to Tcl development in order to fix the problem and will be in
the next patchlevel releases of Tcl 8.5/8.6.

As a consequence if your running a threaded Tcl you cannot use
'fileevent' controlled callbacks. Provided you're doing synchronous I/O
you shouldn't hit the problem
