=head1 NAME

Apache::Session::Informix - An implementation of Apache::Session

=head1 SYNOPSIS

 use Apache::Session::Informix;

 #if you want Apache::Session to open new DB handles:

 tie %hash, 'Apache::Session::Informix', $id, {
    DataSource => 'dbi:Informix:sessions',
    UserName   => $db_user,
    Password   => $db_pass,
    Commit     => 1
 };

 #or, if your handles are already opened:

 tie %hash, 'Apache::Session::Informix', $id, {
    Handle => $dbh,
    Commit => 1
 };

=head1 DESCRIPTION

This module is an implementation of Apache::Session.  It uses the Informix
backing store and no locking.  See the example, and the documentation for
Apache::Session::Store::Informix for more details.

=head1 USAGE

The special Apache::Session argument for this module is Commit.  You MUST
provide the Commit argument, which instructs this module to either commit
the transaction when it is finished, or to simply do nothing.  This feature
is provided so that this module will not have adverse interactions with your
local transaction policy, nor your local database handle caching policy.  The
argument is mandatory in order to make you think about this problem.

This module also respects the LongReadLen argument, which specifies the maximum
size of the session object.  If not specified, the default maximum is 8 KB.

=head1 AUTHOR

This module was written by Jeffrey William Baker <jwbaker@acm.org>.
