Hi Perl Monks. I have a perl script test3.pl. The get function of LWP won't work in the browser until httpd is restarted although it always works in a terminal.

#!/usr/bin/perl

# What's Wrong with LWP::Simple::get ?

use strict;
use LWP::UserAgent;
use LWP::Simple;
use constant URL => 'http://www.google.com';

main();
exit(0);

sub main
{
print "Content-type: text/html\n\n";
   print "Fetching '" . URL . "' with LWP::UserAgent\n<br>\n";

   my $ua = LWP::UserAgent->new();
   my $response = $ua->get(URL);

   if ( $response->is_success )
   {
      my $len = length($response->content);
      print "Retrieved $len bytes\n<br>\n";
   }
   else
   {
      my $code = $response->code;
      print "Failed to retrieve URL: $code\n<br>\n";
   }

   print "Fetching '" . URL . "' with LWP::Simple\n<br>\n";
   my $content = LWP::Simple::get( URL );

   if ( $content )
   {
      my $len = length($content);
      print "Retrieved $len bytes\n<br>\n";
   }
   else
   {
      print "Failed to retrieve URL\n<br>\n";
   }
}

Before I restart httpd

In terminal, I run "perl test3.pl", which gives the correct result, i.e. the get function retrieving the URL.

Content-type: text/html

Fetching 'http://www.google.com' with LWP::UserAgent
<br>
Retrieved 9972 bytes
<br>
Fetching 'http://www.google.com' with LWP::Simple
<br>

However, in a browser (Firefox), I access this script and I get the following:

Fetching 'http://www.google.com' with LWP::UserAgent
<br>
Failed to retrieve URL: 500
<br>
Fetching 'http://www.google.com' with LWP::Simple
<br>
Failed to retrieve URL
<br>

The problem persists if I don't restart httpd.

If I restart httpd, the script works fine in the browser, returning the following:

Fetching 'http://www.google.com' with LWP::UserAgent
<br>
Retrieved 10026 bytes
<br>
Fetching 'http://www.google.com' with LWP::Simple
<br>
Retrieved 10008 bytes

Please note httpd was running even before I restart it.

Please advise me of how to figure out the problem, Apache (httpd), mod_perl, or ... . Thank you Perl Monks.
