Re: Why does back-buttoning to a cgi script-output page yield 'Page expired'?

in reply to Why does back-buttoning to a cgi script-output page yield 'Page expired'?

I'm still a newbie, but I ran into this yesterday. I wanted to be able to return from a sub that required a variable to be set

 if $hidden_string eq "true"{
           &dothis;
        }

To avoid all the problems with hitting the back button, I changed it to this 
 if (defined($hidden_string)){
           $hidden_string = "";
           &dothis;
        }
