Method one, simple comments:
# Here is a comment
# that spans across
# several lines....
Method two, POD:
=pod
Here is a comment
that spans across
several lines....
=cut
Note that these aren't quite equivalent though. The first way is
simpler, and it's how most Perl programmers seem to handle brief (or
maybe not so brief) notes on how the program works. The second way is
intended as documentation, possibly for programmers, possibly for later
users of the script; the second way will respond to the `perldoc`
command -- meaning anyone that can run the script can also examine
comments formatted this way. That may or may not be desirable, which may
be why it seems to be less common than simple # comments.

Are you really expecting to store the contents of one URL to another?
The getstore() function is intended for saving to a file. Try saving to
a file that can be accessed as that URL --
$homepage = "~/public_html/provaperl5.html";
Etc. As far as I know, it cannot be a URL, it must be a file.

It must be a real *file*, not a *page* (though that file can be accessed
as a page, depending on where it is and how your web server is set up).
I'm not sure what you mean by "must be a file ... or ... normal variable
... or ... filehandle"; the way you write this implies that it's one, or
the other, or the third, but that isn't necessarily the case.
