Hi Andy,

So if I have the users choices (that I want to re-display as a list) coming
back in the POST. Once I have turned them into a session variable what is
the best way to re-request the page? Should I just do a redirect or would
some other method be better?

post '/featadd' => sub { # let user enter info

      my $input_hash = {

      game_id => param('game_id'),
      spsrd_chlg_id => param('spsrd_chlg_id'),
      period => param('period'),


      session list_hash => $input_hash;


#re-request the page and display list_hash ??
