apache in win2k
dear all, i just install apache 1.3.26 in win2k. the html documents are running properly but cgi is not running. i have perl v5.6.1 installed. everytime i run a cgi script, the server error_log says "couldn't spawn child process: c:/program files/apache group/apache/cgi-bin/pizza.cgi". this error happens even if i run a simple cgi that prints "hello world". i'm not sure if it has anything to do with the shebang line because as what i found out, windows ignores the shebang line. pls advise. thks Conan
Where is UserAgent.pm
Dear members of the list, I have a question that will probably reveal how little (if anything) I know about perl. Please forgive me if I am asking something akin to "will the sun rise tomorrow" to a perl programmer... I need to use a script on my web server (running RedHat 7.2) that requires me to install MIME-Lite. I downloaded MIME-Lite-HTML-1.8.tar.gz from cpan and tried to install it, as instructed in the README file. However, the testing was unsuccesful, as I was told that: Can't locate LWP/UserAgent.pm in @INC... I assume this is another perl module that I do not have. Could someone please tell me where to find it? (I looked into User and Agent in cpan, but they do not seem to be the ones...) Also, the script I need to use tells me that I can copy the directory MIME into cgi-bin, and that this should contain Lite.pm. Well, nothing with that name appears in MIME-Lite-HTML-1.8.tar.gz, only a HTML.pm. Is this the same thing? Thank you very much for your help Marcelo -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
writting webmail with perl V.S C
Hi all: I am considering which language to write a webmail mail program is a better choice. Is there any article compare the two language developing a cgi program ? Thanks ! Cliff -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Are you reading the data into an array in the script and then printing
the array using interpolation inside double quotes?
print @Array; and print "@Array";. are different. The second will
separate the items with spaces.

RE: nearly got the cookies // debugging suggestion
Here's a sample CGI/Cookies script, originally taken from perlmonks (cLive).
Notice you don't need CGI::Cookie. You may need to refresh once to see the
set cookies. And don't tell my wife about the redheads thing, she's a
brunette. :)
#!/usr/bin/perl-w
use strict;
use CGI;
use CGI::Carp 'fatalsToBrowser';
my $cgi = new CGI;
# grab existing %cookie
my %cookie;
for ($cgi->cookie()) {
$cookie{$_} = $cgi->cookie($_);
}
# set a couple of cookies;
$cookie{'ID'} = 123456;
$cookie{'preferences'} = "redheads";
$cookie{'LoginName'} = "Calaban";
$cookie{'Other_cookie'} = "whatever";
# create cookies for CGI
my @cookies;
for (keys %cookie) {
push @cookies, $cgi->cookie( -name => $_,
-value => $cookie{$_}
);
}
# print amended header
print $cgi->header(-cookie=>[@cookies]),$cgi->start_html(-title=>'Login');
# use our hash to check "cookie"
if(defined(my $cookieHolder = $cookie{'LoginName'})){
print $cgi->h3("Retrieved cookie named LoginName: $cookieHolder");
}
else{
print $cgi->h3("No cookie retrieved.");
}
# display all stored
print $cgi->h4('Stored Cookies');
for (keys %cookie) {
print "$_ = $cookie{$_}".$cgi->br;
}
Should show:
Retrieved cookie named LoginName: Calaban
Stored Cookies
ID = 123456
preferences = redheads
Other_cookie = whatever
LoginName = Calaban
I'm learning CGI myself so if anyone else wants to pitch in please do so.

RE: session id
I usually use Session::Apache for that. It will allow for the creation of session ID's, storing data, and retreival of data. You will need to set up a table in a database, and then put some code in each page to fetch the session ID from the querystring or cookie so that it can initialize the session object. It's a little tricky, but will do what you want.

my @Data = ('one ', 'two ', 'three

Thanks so much for spending so much time on this. When I decided that this
sounded like a "simple" project to help me learn Perl, I obvously had no
idea what I was getting myself into.
Any more ideas?

Perl, Apache & undefined subroutine
Hi, I am having a problem on a particular server with a subroutine being 'undefined' most (but not all) of the time. The error that shows up from apache is: Undefined subroutine &Apache::ROOT::perl::query_2epl::ReadParse called at /usr/local... line 13 The subroutine, &ReadParse() is provided by cgi-lib.pl (v2.18). cgi-lib.pl resides in the same directory as the perl script which does: require "cgi-lib.pl"; followed by the &ReadParse(). I have tried different paths (e.g., ../cgi-lib.pl) with no difference in behavior. I don't have any hard statistics, but the error is very random. Sometimes there isn't an error, often times there is. If I click reload "enough" times the page will eventually load without error. The strange thing is that I have the same setup on another server (different scripts but doing the same kind of thing) and there is never a hiccup. The problem server is running Redhat 7.2 and has exhibited the problem with the provided rpm versions of apache, perl, etc. as well as with recent versions that I downloaded and installed (originally it was Apache/1.3.20 (Unix) (Red-Hat/Linux) with perl 5.6.0 and mod_perl as a DSO, now it is Apache/1.3.23 (Unix) with perl 5.6.1 and mod_perl compiled into apache). The working server was running Redhat 7.1 with the provided rpm versions of apache, perl, etc. but is currently running SuSE 7.3 with provided apache, perl, etc. ATM I don't have access to the machine to tell what the various versions are. I would really like to not have to reload a page fifty times just to get the script to run correctly; does anyone have any ideas?

according to a 'view source' on the above url, your hidden input params
do indeed have a new line on the end.
try this (instead of chomp):
foreach (@Draw) {
s/\s+$//g; # remove all whitespace at the end of a row
print "\n";

well i don't know offhand - i'd have to examine what's in @Draw. i'd
suspect you may have more in there than chomp() can handle. can you
post an example portion of @Draw that displays the strange behavior?
btw, your loop can be rewritten as such:
foreach (@Draw) {
chomp;
print "\n";
}
or like this:
map {
chomp;
print "\n";
} @Draw;
without all that $item/$counter stuff. i don't understand what the
$counter is for anyway since you're setting it to 0 on each loop iteration.
