Custom 500 Error Script
Please forgive me if this isn't entirely a perl question. I am able to use
the .htaccess file on my server to forward any 500 errors to a custom script
to handle them. I'm trying to create a script that notifies me when a user
gets a 500 error message (at least while still in beta). What I am finding
is that when the .htaccess file forwards the user to the custom script (in
this case, 500.cgi), I can't collect the name of the page (or the query
string) of the page that caused the 500 error. $ENV{HTTP_REFERER} returns
the page that the user clicked the link or submitted the form from, and
$ENV{SCRIPT_NAME} returns 500.cgi.
Does anybody have any ideas on how to collect the name of the malfunctioning
script?
Thanks,
Todd

Re: Prints the code
Thanks for your reply. The problem was apparently with vqServer using the Sun JVM(which I have here) I could have changed and used Microsoft's JVM, but I installed the Apache server instead.

Re: Custom 500 Error page
I don't think this is possible because I don't think you could find the
referer of a referer with a script.
The referer of your 500.cgi script is page b, so ...

Subject: Custom 500 Error page
I use a shared hosting account that allows me to customize error messages
using a .htaccess file. What I would like to have happen is for my custom
script (500.cgi) to be able to send an email to me (at least during beta)
about the problem. I'm finding that when the user submits data on page A to
page B, which has an error and forwards the user to 500.cgi, I can't pull
data for page B out of the %ENV data. $ENV{SCRIPT_NAME} returns 500.cgi
and $ENV{HTTP_REFERER} returns page A. Is there any way for me to find the
name of the offending script (page B) and the corresponding query string?
Is there something I can add to the .htaccess file that would supply that?
Thanks,
Todd

FW: Cgi Win xp Perl
I am running on a windows xp pro desktop with iis installed. I have
active state Perl installed and have been using it with out a problem. I
just started to play with cgi and I am having a lot of problems getting
it to work right. I have a static html form that's action calls the
following script. When it I hit submit all it does is display it as if
it was a text file. If I rename it to .pl then it tries to download it.
However if I have just call another test cgi script that displays some
html then it runs fine (also named .pl) with one exception it tells me
that it is to late to do -T.
So basically I need to find out how to call this script from my form and
have it execute. Second I need to find out how to get .cgi scripts to
load instead of displaying or trying to download. Third I need to know
how to pass the -t to the compiler before my script executes. (I am
assuming this is a problem with Perl on windows not using the shebang.
Even though -w works odd.)
#!/usr/bin/perl -w
use strict;
use CGI;
my $q=new CGI;
print $q-header (text/plain);
print These are the parameters I received:\n\n;
my ($name, $value);
foreach $name ($q-param){
print $name:\n;
foreach $value ($q-param($name)){
print \t$value\n;
}
}

Post Method versus Get Method
I know the POST Method the data is sent to STDIN, and GET method the data is attached to the URL and then submitted. When and why would you want to use the GET method versus the POST method. Is is because of firewalls? or what? I would appreciate any input on this subject. Thank You.

RE: Post Method versus Get Method
There are many reasons to choose one or the other. A good one for POST is file uploads, where the input values could be very very large (think mega or giga bytes of data) or binary which would have to be encoded and then unencoded in some manner, whereas this is less of a problem over a stream. POST however requires more user interaction, that is submitting a form, etc. Where a GET is just a simple link, which makes building dynamic sites easy, for instance where a CGI prints links to a page that is different for each user, rather than requiring each of those links to be a form, a user can just click, and they unknowingly just submitted a GET to a CGI that then generates another dynamic page (sure this can be done with cookies but who needs the hassle, and there is a limit to how many and how large cookies can be). This is a rather broad question and generally makes more sense with experience http://danconia.org On Tue, 07 Jan 2003 16:17:36 -0500, Susan Aurand [EMAIL PROTECTED] wrote: I know the POST Method the data is sent to STDIN, and GET method the data is attached to the URL and then submitted.

Open2 Spawn-Waitpid()
Ok here is what i have
:
the error msg that the script prints afther it have reached 64 processes is:
open2: IO::Pipe: Can't spawn-NOWAIT: Resource temporarily unavaliable at
msg_cracker.pl line 443
the part of the code is this
}
close TEMPFILE;
} elsif ($Param[1] eq '2wayproc') {
$ExtPid = open2(*ExtReader, *ExtWriter, $TempValue );
shout ('debug',OPEN2: Two-way process with PID $pid spawned.);
select(ExtWriter); $| = 1; select(STDOUT);
}
return;
A friend of mine told me that he did this to his code..
Suppose you run the child process in a loop like I did :
LOOP: while (condition) {
eval { $pid = open2($FHFROM,$FHTO,$Exe,@Params); };
if ($@) {
# then there is an open2() error and error code/message is in $@
}
unless (defined $pid) {
# then the child could not be started for some reason
}
# Now we talk to the child, the child does whatever it has to do and stops
# When we're done ..
# Close up our pipes, collecting status on the way
# By the way, I don't know on which close() we collect the status,
documentation doesn't say
unless (close $FHTO) {
$status = $? 8; # get program exit code ?
# etc...
}
unless (close $FHFROM) {
$status = $? 8; # get program exit code ?
# etc...
}
sleep 1; # give it time to exit (maybe)
# And here is the essential part to avoid the Resource not available..
error
:
# waitpid() cleans that child process's remainders out of the process table,
# which otherwise fills up and eventually leads to the resource not
available
error
$status = waitpid($pid,0);
# I suppose should also get the child exit code in $status
} # end while LOOP
BUT i changed some thngs to use in my prog but it did not work...
Please can someone help me
