Correction: redirect() usage is NOT causing the problem. Every call of
a controller function also executes
1) general parts of the model (db.py)
2) general parts of the controller (default.py)
3) the requested function in controller
In my case every click to an menu function adds another multiple for
log entries.
Thinking about the response.menu example which gives you different
menu options depending on the user being logged in or not I'm
convinced that the general controller sections are executed before
each requested function. That's good for the dynamically changing menu
and other needs.
For a log file function which should be available for the entire
controller I need to make sure its executed only once. Is there a
simple way to do that or a different way to achieve a log file
function (similar like my example up in this thread) available for the
entire controller?
Thanks,
Hans
