DESCRIPTION

URL:List is a module which helps you with distributing a list of URLs "evenly" based on the URLs' host name, domain name or TLD (top-level domain).

This can be useful for crawlers, ie. giving out a list of URLs within specific domain names to different worker robots.

METHODS

add( $url )

Add a URL to the list.

all

Returns an array reference of all the URLs in the list. This list can include duplicates.

count

Returns the number of URLs in the list, including eventual duplicates.

distributions

Returns a hash reference of all the possible distributions. This method should not be used directly, but is provided because it's a helper method for the methods mentioned below.

distributed_by_host

Returns a hash reference where the key is the host name, like "www.google.com", and the value is an array reference to the host name's URLs.

distributed_by_domain

Returns a hash reference where the key is the domain name, like "google.com", and the value is an array reference to the domain name's URLs.

distributed_by_tld

Returns a hash reference where the key is the top-level domain name, like "com", and the value is an array reference to the top-level domain name's URLs.
