using http::recorder

My apologies for my newbie question, but I am looking at http::recorder, and
the readme guide says this:

my $proxy = HTTP::Proxy->new;
# set HTTP::Recorder as the agent
my $agent = HTTP::Recorder->new( file => "/tmp/tmpfile" );
$proxy->agent( $agent );
$proxy->start();

I am wondering if I place the proxy in:
$proxy->start('proxy:port');
?

I am also looking at using selenium with javascript to follow a link that is
a javascript link where the text regex is:

follow_link( text_regex => qr/Articles/i );

Anyhelp will be greatly appreciated
