By the way, have you ever considered adding a pre-parsing

(say, up to the first line of code) and place them before
the actual subroutine that will become main and will denote
the script itself? That could be a life-saver! I believe
that's how the ATG-Dynamo people did it... Dynamo is a Java
(no booing please) -based app server where the scripts
(identical to jsp's) are precompiled as their own "classes"
and then executed. In their case I believe they do that
preparsing I mentioned except that in Java I don't think
it makes much of a difference! Oh well, Perl : 4654574,
Java : 1 !
I don't think I would be able to successfully parse out
subroutines without writing a complicated parser, but its
an interesting idea. I could have the UseStrict setting
trigger an error_log warning recommending to move subs
to a perl library possibly if I find a \nsub\s+\w+\s*{\s*\n
kind of expression in the ASP perl code.
I hate to digress again but although I understand the
"closure" deal, why does it persist? In one execution I
understand having that problem of not refreshing the
value but why in subsequent executions as well? Shouldn't
those values disappear by that point? I had it where I
was adding elements to an array in the $arr[$#arr] fashion
and if I pressed the refresh button fast enough the array
would grow in size by the size of the original array! I'm
pretty sure what server thread you're on makes a difference.
So if you have three threads with the underlined being the
active one here's what would happen to the array size if I
added ten elements to $arr by saying $arr[$#arr] = x
The problem/benefit of mod_perl is that things persist so
variables don't get cleared, and my closures don't get
recompiled. Your array growing problem sounds like one
that "use strict" programming will take care of because
if you initialize your array with my @arr; then it should
be cleared just fine every script execution.

Why it is so complicated ?
I am trying to install apache support for ASP (using win95). I have spent many days in downloading+reading+trying etc... without results. It seems as if it is the purpose of some persons to make it complicated. Is it a hard task to make one file (exe) to make it automatic installing ? Assil
dir_config and Apache::Table confusion
If I do this:
$r-print($r-dir_config('key'));
Then key is printed.
If I then do this:
my $tab = $r-dir_config;
$r-print(Dumper($tab)); # Using Data::Dumper
I get '$VAR1 = bless( {}, 'Apache::Table' )';
It's empty, how come?

Probably because keys doesn't return the keys of an Apache::Table object,
since it is implemented in C.

I'm not quite sure it's that simple. If you replace dir_config()
with headers_in() which also return an Apache::Table object you get a
sane result from Dumper().
Also, when using dir_config as in my first posting $tab-{$key}
returns nothing (undef?), but (as I said) dir_config($key) returns
correctly.

Uploading File
New to mod_perl and am having problems writing a script to allow our creative department the ability to upload banners to a directory on our server. I'm using Apache::Request, but keep getting stuck and am ready to pull my hair outanother problem i have to deal with is that the banners have to go into different directories within the banner directory depending on what size they are. Can anyone give me any hints or tips? Or if anyone has a chunk of code I could possibly use I would really appreciate it. I'm ready to give up! __ Do You Yahoo!?

To build packages that work seamlessly on many different platforms isn't easy, especially for Win32, but many people here have put a lot of effort into this - they make their lives harder so yours can be easier ... Is it a hard task to make one file (exe) to make it automatic installing ? Using the CPAN.pm module to install things is very good advice - Apache-ASP should build and install cleanly with it. Alternatively, if you're using ActivePerl (the 600 series, based on Perl-5.6.0), there's a mod_perl package you can try - install it as (on one line) ppm install http://theoryx5.uwinnipeg.ca/ppmpackages/mod_perl.ppd and then ppm install http://theoryx5.uwinnipeg.ca/ppmpackages/Apache-ASP.ppd You might need some additional packages for ASP, depending on your setup - these can also be installed by the ppm utility from ActiveState's site (see http://www.activestate.com/ppmpackages/ for a list of available packages). best regards, randy kobes
Re: OT: Server-push client page reload
Hi
type: multipart/x-mixed-replace
use CGI::Push qw(:standard)
do_push(-next_page=\draw_a_page)
sub draw_a_page {
my ($q,$counter)= @_;
return undef if $counter 100;
my $time = localtime();
return start)html(),
h1('test'),
'This page is caaled $counter times',
hr,
$time,
end_html;
}
This is what I used once just as a test , but not under mod_perl.
Netscape does support it. I understand that you have to set up channels
under MS.. Not any idea about that. Could somebody point me some
direction regarding channels.

You know those online web-based tech support chat systems? Its commonly frame
based, but its just like IRC, but over HTML. when a user posts a message it
immediatly pops up on the chat frame, and you submit your message through a
regular-ol' HTML form. I don't think this is an applet, because this works in all
sorts of browsers. I think its javascript, but I'm not sure. My main question, is
when the server knows that a new message has been posted, how does it push that new
page out to the client web browser? I'm used to all page-views originating from the
client...not the server.
Any ideas?

Finding Consultants on adding Perl Modules
Hi: Do you have a list of consultants who have experience in adding Perl Modules to Apache? We have a business need for some modules, such as Storable, and would be willing to contract for them. Is there some mechanism in general for finding Apache consultants? There are other areas we could use some help in, but as you know, many people put Apache on their resume if they have even read your web site! I'd appreciate any help you could give on this.
