We are currently performing a project to convert from ActivePerl/IIS
to Apache::ASP and have
run across issues with variables behaving strangely. After searching
the web, I have a couple
of issues I would like some advice on.
1. Variable scope ...
>From the Apache::ASP page (Style Guide):
"One of perl's blessings is also its bane, variables do not need to be
declared, and are by default globally scoped. The problem with this in
mod_perl is that global variables persist from one request to another
even if a different web browser is viewing a page."
Our problem is the original authors of the code assumed variables are
not globally scoped.
Q1.1: How come in other languages, the scope of the variable is
assumed to be for the page unless
defined otherwise (e.g. PHP, ActivePerl, VBScript)?
Q1.2: Is there a configuration option or easy way around this issue?
2. Subroutines ...
>From the Apache::ASP page (Style Guide):
"DO NOT add subroutine declarations in scripts. Apache::ASP is
optimized by compiling a script into a subroutine for faster future
invocation."
We have ActivePerl Perlscript pages with
[sample.asp]
<%@ LANGUAGE = PerlScript%>
<!--#include virtual=[include.asp]-->
<%
my $foo = 1;
my $bar = 2;
my ($value) = &getValue($foo, $bar);
$Response->Write("Value = $value<br>\n");
%>
[end sample.asp]
[contents of include.asp]
<%
sub getValue
{
my ($foo, $bar) = @_;
my $value = $foo * $bar;
return $value;
}
%>
[end include.asp]
Q2.1: Since this sub is included in sample.asp, is it considered a
subroutine within a subroutine?
Q2.2: Is there an easy way to convert include.asp to include.pm so I
can use "use include.pm" in our scripts?
Q2.3: Does Apache::ASP support #include virtual=...? It only seems to
work with #include file=...
