Hello Monks, I am trying to understand the use of Apache::Session::MySQL and I have what appears to be a couple of simple questions. I have found the following code in a number of pages on the Net as an example for setting up sessions. My question is how does the code below know where to find my table and a field to update with in my table? Is 'dbi:mysql:sessions' supposed to be replaced with 'DBI:mysql:database=$database;host=$hostname;port=$port'? I have a feeling I am misunderstanding something somewhere, but I can't figure out what it is. Thank You. 
# pull in the required packages
use Apache::Session::MySQL;
use Apache;

use strict;

# read in the cookie if this is an old session
my $r = Apache->request;
my $cookie = $r->header_in('Cookie');
$cookie =~ s/SESSION_ID=(\w+)/$1/;

# create a session object based on the cookie we got from the
# browser, or a new session if we got no cookie
my %session;
eval {
    tie %session, 'Apache::Session::MySQL', $cookie,
        {DataSource => 'dbi:mysql:sessions',
         UserName   => $db_user,
         Password   => $db_pass,
         LockDataSource => 'dbi:mysql:sessions',
         LockUserName   => $db_user,
         LockPassword   => $db_pass,
        };
};
if ($@) {
    # could be a database problem
    die "Couldn't tie session: $@";
}

# might be a new session, so let's give them their cookie back
my $session_cookie = "SESSION_ID=$session{_session_id};";
$r->header_out("Set-Cookie" => $session_cookie);
