Why does the following code process the same file in an infinite loop? I want it to stop processing the file after a single iteration. 

#!/usr/bin/perl
use strict;
use warnings;
use WWW::Mechanize ;
my $mech = WWW::Mechanize->new();

my $txt_url ;
my $pdf_url ;
my $html_url ;
my $output ;
my @output ;
my $file_content = "D:/Perl/Perl output/garbage_content.csv" ;

my $get_file = "http://securities.stanford.edu/filings-case.html?id=10
+1092";
my $filename = "file_output_101092" ;
my $response = $mech->get($get_file,
':content_file'=> $file_content,);
open my $fh, '<', $file_content ;

         
  while (<$fh>) {
    chomp;

    my $i =1 ;
    if(index($_,".txt")>=0) {
        $txt_url = $_ ;
    }else {
        if(index($_,".pdf")>=0) {
            $pdf_url = $_ ;   
        }else {
            if(index($_,".html")>=0) {
                $html_url = $_ ;   
            } 
        }
    }

    if (($txt_url)|($pdf_url)|($html_url))
    {
        $output = join ",", $filename, $txt_url, $pdf_url, $html_url ;
        push @output, ($output) ;
        foreach (@output) {
            print "Round $i\n " ;
            print "$_\n" ;
            $i++ ;
           #sleep(1) ;
        }
    }
}
close $fh ;
