in thread LWP - 500 Internal Error

Hi and Thank for the link, Was my thread, vry interesting too - but i didn't think I could start from there anew. Anyway, I tried adding the sfprint debug, doesn't work for me yet. 
# !C:\Perl\bin
use strict;
use warnings;
use LWP::UserAgent;

@ARGV = qw[  http://www.eserve.com.sa/ ];

my $url       = shift or die "URL expected\n";
my $useragent = LWP::UserAgent->new;

$useragent->proxy(['http', 'ftp','https'], 'http://192.168.5.5:8080/')
+;
$useragent -> timeout( 20 );

my $request   = HTTP::Request->new( GET => $url );
my $response  = $useragent->request($request);
my $err = sprintf "(%d)(%s)(%d)(%s)\n", $!,$!,$^E,$^E;
print $useragent->proxy('http'),"\n";
print $response->status_line, "\n";
print "Err : $err \n";

    200 OK means there was no error

      Hi,

      yes, that particular link worked fine, 200 OK. What I meant to ask about was the error 

      Err : (9)(Bad file descriptor)(0)()

      [download]

      as the output of 

      my $err = sprintf "(%d)(%s)(%d)(%s)\n", $!,$!,$^E,$^E;
print "Err : $err \n";

      I was expecting as mentioned in the link you sent that this particular part of the code would work like a sniffer and decipher more information as to why it fails

      Really appreciate the feedback

        Like I said in that link you use $err to get more info about which Unknown Error it is. You only look if the request fails, and only because "Unknown Error" is diagnostically useless. $! expands to "Unknown Error" for too many errors, like

        (100)(Unknown error)(100)(Cannot create another system semaphore)
(101)(Unknown error)(101)(The exclusive semaphore is owned by another 
+process)
(102)(Unknown error)(102)(The semaphore is set and cannot be closed)
(103)(Unknown error)(103)(The semaphore cannot be set again)
(104)(Unknown error)(104)(Cannot request exclusive semaphores at inter
+rupt time)
(105)(Unknown error)(105)(The previous ownership of this semaphore has
+ ended)
(106)(Unknown error)(106)(Insert the diskette for drive %1)

        You're also supposed to look at print $response->dump,"\n"; on error, because it might contain more than "Unknown Error"
