I am using HTML::Template, CGI::Application CGI::Session to set and use session variables and it works great. However, I need a better solution than the one below for setting the default value and to check if I need to set the variable. The code works ok, but as the number of session variables increase so does this ugly piece of code. 
if($post{'page'}){
  $self->session->param('page' => $post{'page'});    
} elsif( (!$post{'page'}) && (!$self->session->param('page')) ) {
  $self->session->param('page' => 1);
} else {
  $self->session->param('page' => 1);
}

I know I can set the default value on the TMPL_VAR's but I can't apply that to all variables. Anyone have a cleaner solution?
