NAME

LWP::UserAgent::RandomProxyConnect - A LWP::UserAgent extension for becoming an omnipresent client.

VERSION

Version 1.10

SYNOPSIS

This Object does exactly the same than the LWP::UserAgent class with a new useful feature: it can make each HTTP request throw a different proxy each time. Also, a few methods improve the proxy list management, and makes the iterative connections faster.

CONSTRUCTOR

new()

When this class is invoked as:

my $obj = LWP::UserAgent::RandomProxyConnect->new

several test will be made. First, the class must find a valid file with a proxy list, if not, this object will stop. This file must be placed in the environmental variable $ENV{PROXY_LIST}.

However, the class can be invoked as:

my $obj = LWP::UserAgent::RandomProxyConnect->new(-proxy_list => $proxy_file_path)

the created object will search the file at the specified path.

Whatever the method you use to invoke the class, the object will stop if the specified file doest not exists, is not readable or there is no proxy found into it.

Furthermore, you can add as argument all the properties described at LWP::UserAgent

THE EXTENDED REQUEST METHOD

request

This method is exactly the same than LWP::UserAgent->request LWP::UserAgent with the implemented proxy-change in each request. It obiously make the connection slowler. NOTICE: Only http and https protocols are allowed.

env_proxy

This function overrides the original function in order to avoid the static proxy configuration

ATTRIBUTES

As inherited class from LWP::UserAgent, it contains the described attributes at LWP::UserAgent, but there is some new attributes in this class:

proxy_list (Default value: $ENV{"PROXY_LIST"})

The proxy_list attribute contains the string with the proxy list file path. The accessor method:

my $proxy_list = $obj->get_proxy_list;

returns such string.

Also it can be set by the mutator method:

$obj->set_proxy_list($new_proxy_list_value);

protocols_allowed (Default value: ['http','https'])

Protocols allowed to stablish the communication.

protocol (Default value: 'http')

The protocol used to communicate. e.g.: if the specified protocol is "ftp", the absolute proxy URI will be:

ftp://proxy.url.or.ip:port/

METHODS FOR HANDLING THE PROXY LIST

renove_proxy

This function returns a new random proxy from the list. This return value is a string with the format: <proxyUrlorIP>:<port>. This is just a query for a single request.
