Here are a few pointers.
- When you use or require a module it gets placed in %INC. If you use or require it elswhere then
perl just ignores you as it is already loaded
- With CGI.pm or CGI::Simple when you create a
new CGI object all the data on STDIN is read in (this gets there when you POST)
so you can ONLY read this data once as once the data is read in it's gone. Thus you
MUST only create one object if you are using POST. With GET the data is stripped off
$ENV('QUERY_STRING') so you could have more than one (accurate) object.
- To pass information between modules you have objects, accessor methods and globals to play with
