when i use $cgi = $session->load_param(); all cgi-params that are stored in (a previous) session will be overwritten. at the moment i am looking for an easy way to migration my apps to CGI::Session. inserting a few lines like dealing with sessions would be great. but when i am using the load_param the it is not possible to detect in an easy way that on paramter has changed. eg. if there is a name field. i can store it via save_param in $session. let's say the user has not entered all data, so i redisplay the form and ask for "name". now the user change name and enter all the other data. i won't recognize the name change, unless i check every single param from $cgi before storing it in $session. do i miss something? thanxs makrus
