[ic] Cookies-Enabled Checking Routine

[G Guttero]

>>Why is the cookies-enabled checking routine in the demo like this:

>>	[/elsif]
>>	[else]
>>		[set tried]1[/set]
>>		[bounce href="[area ord/basket]"]
>>	[/else]
>>	[/if]
>>
>>Why isn't it simple like:
>>
>>[if type=explicit compare="q{[read-cookie MV_SESSION_ID]}"]

I totally understand what you're saying there.  But why bother with the 
scratch variable "tried" and the bounce?  I just want to make sure I'm not 
missing something.  Why not:

[calc]
my $cname = $Config->{CookieName} || 'MV_SESSION_ID';
$Scratch->{have_cookie} = $Tag->read_cookie($cname)
and delete $Scratch->{tried};
return;
[/calc]
[if scratch have_cookie]
[else]No cookies?[/else]
[/if]
