Hi.
I think there is another email address I would use for this kinds of question. If so,
much appreciate if someone could let me know.

Here is my question.
I have created a module that will lookup the database and determine if I should forward,
redirect, or reject the request.
Since there is no switch statement in the script, I am wondering if I would save the
"action" into a static variable and export a function to check and determine the
action.
I know the above could be done and it should be ok as we do a fork - should duplicate the
memory as well.
I would much appreciate if someone could give me a YES or NO answer or any idea how this
is done.
Yes. :-)
To see if you don't use a previously saved value, you can check against
the message id (which is unique per process).
e.g.:
/* set var */
saved_id=msg->id;
saved_value= ...;
/* check val */
if (saved_id==msg_id){
return f(saved_value);
}else{ /* no value was saved for this message, use the default one */
return f(default_value);
}
