## SYNOPSIS
     require [WWW::RobotRules::AnyDBM_File](https://www.chedong.com/phpMan.php/perldoc/WWW%3A%3ARobotRules%3A%3AAnyDBMFile/markdown);
     require [LWP::RobotUA](https://www.chedong.com/phpMan.php/perldoc/LWP%3A%3ARobotUA/markdown);

     # Create a robot useragent that uses a diskcaching RobotRules
     my $rules = [WWW::RobotRules::AnyDBM_File](https://www.chedong.com/phpMan.php/perldoc/WWW%3A%3ARobotRules%3A%3AAnyDBMFile/markdown)->new( 'my-robot/1.0', 'cachefile' );
     my $ua = [WWW::RobotUA](https://www.chedong.com/phpMan.php/perldoc/WWW%3A%3ARobotUA/markdown)->new( 'my-robot/1.0', '<me@foo.com>', $rules );

     # Then just use $ua as usual
     $res = $ua->request($req);

## DESCRIPTION
    This is a subclass of *[WWW::RobotRules](https://www.chedong.com/phpMan.php/perldoc/WWW%3A%3ARobotRules/markdown)* that uses the AnyDBM_File package to implement
    persistent diskcaching of robots.txt and host visit information.

    The constructor (the new() method) takes an extra argument specifying the name of the DBM file
    to use. If the DBM file already exists, then you can specify undef as agent name as the name can
    be obtained from the DBM database.
