Dear list members
Maybe the perl-module-authors would be the more appropriate list for my
question(s), but here are people confronted with the same tasks to solve when
programming web applications, so...
Some of the tasks always to be solved in an interactive webapp:
a) validate/sanitize user input
Data::FormValidator can be a little daunting at first, but it's very
powerful and flexible. After some use it becomes your best friend ;-)
b) differentiate between persistent parameter values and "volatile" ones (the
latter meaning a value only used along one request/answer)
You're talking about session values and request values.
I think you should a search for 'Session' on search.cpan.org and try out
some modules, especially those in the Apache:: namespace.
Also, read the documentation of some of them even if you don't try them
out: you'll learn a lot about the problem(s) you are trying to solve.
