That's good to hear. Note that some features get turned on with the
CollectionItem setting to activate certain collection type behaviors.
This has facilitated others port before.

ServerVariables are web server dependent environment availables,
equivalent to %ENV in Apache::ASP. So what Apache sets seems to
differ greatly from what IIS sets.
What you can do to make a compatible environment is:
# in global.asa
sub Script_OnStart {
my $all_http = 'something';
$Request->ServerVariables('ALL_HTTP', $all_http);
}
This will set up for you the ALL_HTTP variable to your specs
for all ASP scripts, and you can further customize your environment
as you see fit.
Once you have figured out all the environment variables that are
missing and how to construct them to make things look like IIS,
then we might create a PerlSetVar ServerCompat IIS setting that
sets these up for you without having to use Script_OnStart event.

If you had "use strict;" turned on, these my-less variables would have
created compile time errors. This is a common mod_perl issue. In
Apache::ASP, this is facilitated by setting
PerlSetVar UseStrict 1
which makes strict all scripts,includes, & global.asa I believe.
I have considered having this setting turned on by default, but
haven't figured a good way to do this, and keep backwards
compatibility.

I'll add a section like this to the FAQ.
Thanks.
