What freeze does is called serialising. You could serialise using Storable, but you didn't indicate any reason to do that. 
use URI qw( );
sub url_freeze {
   my ($base_url, @args) = @_;
   return URI->new($base_url, 'http')->query_form(@args);
}

my $url = url_freeze('/cgi-bin/details', %args);

I may have the exact usage a bit off.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
