I have a very basic question regarding Apache/mod_perl. I have a web
application running under mod_perl with Apache::DBI enabled that uses
mysql database. For certain kind of requests alone I want to enable
transaction at the beginning of the request and at the end of request,
commit and stop the transaction if the transaction was turned on.
All modules use the following code for getting database connections
$dbh = DBI->connect_cached($dsn, $user, $password,
                           {RaiseError => 1,
                            AutoCommit => $transaction
                           });

Can I be sure that when a request is using such a transaction enabled
database connection handle, another request cannot get the same
transaction enabled database connection? As per the Apache::DBI
documentation, it only keeps connections persistent on a per process
basis. So I understand that the answer is yes, but just wanted to confirm
anyway.

Thanks very much
