如何使用perl 模組 LWP::UserAgent 時，不要每次呼叫post時，會重新連線一個session

my $browser = LWP::UserAgent->new(ssl_opts => { verify_hostname => ''},
                                  cookie_jar => HTTP::Cookies->new,
                                  requests_redirectable => [],
                                  timeout => 10,
                                  agent => "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:67.0) Gecko/20100101 Firefox/67.0"
                                 );
