Here's something super cheezy I just wrote up as a quick excersize for myself. It does what you ask for... 

use strict;
use IO::Socket;

my $server = IO::Socket::INET->new (
      Proto => "tcp",
      LocalPort => 3000,
      Reuse=>1,
      Listen=>10 );

my ( $pid, $host, $date );

$date = scalar localtime();

sub spawn_srvr {

   my ( $vers, $page, %hdrs );

   while (<$host>) {

      /^(GET)\s(.*)/  && do {
         $hdrs{$1} = $2;
         next;
      };

      /^((\w|-)+):(.*)/ && do {
         $hdrs{$1} = $3;
         next;
      };

      /\n/ and do {

         ( $page, $vers ) = split(/\s/, $hdrs{'GET'}, 2);

         if ( open(FH, "<$page") ) {

            print $host <<EOF;
HTTP/1.1 200 OK
Date: $date
Server: LameWeb
Connection: close
Content-Type: text/html

EOF

            print $host $_  while ( <FH> );

         } else {

            print $host <<EOF;
HTTP/1.1 404 Not Found
Date: $date

Connection: close
Content-Type: text/html

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

EOF
         }

      last;

      };
   }

   kill(9, $pid) && print "killed pid: $pid\n";

}


while () {
   $host = $server->accept();
   if ($pid = fork()) {
      spawn_srvr();
   }
   $host->close;
}
