# Apache::Session::MySQL::NoLock(3pm)

An implementation of Apache::Session::MySQL without locking

## NAME

Apache::Session::MySQL::NoLock - An implementation of Apache::Session::MySQL without locking

## SYNOPSIS

```
 use Apache::Session::MySQL::NoLock;
 #if you want Apache::Session to open new DB handles:
 tie %hash, 'Apache::Session::MySQL::NoLock', $id, {
    DataSource => 'dbi:mysql:sessions',
    UserName => $db_user,
    Password => $db_pass,
 };
 #or, if your handles are already opened:
 tie %hash, 'Apache::Session::MySQL::NoLock', $id, {
    Handle => $dbh,
 };
 To configure the non-locking session store in RT (what I use this module for),
 put the following into your C<RT_SiteConfig.pm> module:
    Set($WebSessionClass , 'Apache::Session::MySQL::NoLock');
```

## DESCRIPTION

This module is an implementation of Apache::Session. It uses the MySQL backing store and the Null locking scheme. See the example, and the documentation for Apache::Session::Store::MySQL for more details.

## WARNING

This module explicitly **DOES NOT DO ANY LOCKING**. This can cause your session data to be overwritten or stale data to be read by subsequent requests.

This **CAN CAUSE LARGE PROBLEMS IN YOUR APPLICATION**.

## AUTHOR

This module was written by Tomas Doran \<bobtfish@bobtfish.net\>.
