RE: [Tclhttpd-users] sessions

[Raul E. (wizardteam) <ra...@wi...>]

There are 2 ways to store sessions, one is using arrays (wich will eat so=
me
memory if you dont clean those variables periodically, ie var1(session),
var2(session), var3(session)), or the common way which uses temprally fil=
es
in /tmp.  However, keeping global variables cant be mixed as tclhttpd doe=
s
one at the time request (with no threads enabled), unless you dont reset
your variables.  For that case, ncgi package is very handy instead of usi=
ng
global variables.

The best and clean way to do session its as explained by Sean Woods in th=
e
last message.  Using one cookie generated with a random string (as the
ticket number or traking string) that matches against a sql record in whi=
ch
you can store must of the private environment for the session (usually th=
e
username).

  Hi Jeff,

  The problem with session package, i think it is not complete, after
creating a session, the user suppose to have his own state i.e variables,=
 it
is not just only tracking the user  "how is the user" because this can be
done by hidden fields, after creating session  still all the forms variab=
le
are in the global scope that's mean that if two users are inserting recor=
ds
at the same time, the records will mix up

    There are a few examples of using TclHttpd's session
    module on the wiki
