You can control the number of retries by using LWP::UserAgent::Determined. I set the timing string at 5 seconds, 10, and 20. I also added the codes that I wanted it to retry.

#!/usr/bin/perl

use strict;
use warnings;
use LWP::UserAgent::Determined;

my $url = 'http://www.google.com';

my $browser  = LWP::UserAgent::Determined->new( 
               cookie_jar => '' );
my $timing_string = $browser->timing("5,10,20");
my $http_codes_hr = $browser->codes_to_determinate();
$http_codes_hr->{408} = 1;
$http_codes_hr->{500} = 1;
$http_codes_hr->{567} = 1;
$browser->before_determined_callback( sub {
    print "Trying ", $_[4][0]->uri, " at ",
    scalar(localtime), "...\n";  
});     
$browser->after_determined_callback( sub {
    print "Just tried ", $_[4][0]->uri, " at ",
    scalar(localtime), ".\n";
});   

my $response = $browser->get( $url );
print "That gave: ",$response->status_line, "\n";
