What you're seeing is what happens when you call print header twice in one CGI session. You're not doing that only because you're rolling your own with the print "Content-type:..." statement.

The solutions, as I see it are:

• Keep a variable with the cookie, and replace the printing of the template with

      print header(-cookie=>$cookie,-type=>'text/html');
      print $template->output();

• Have a "smart" print_header subroutine that knows if a header has been printed in that session yet, and what the type was set to. That routine can warn you if you're attempting to set a new type.It can also warn you if you try to set a cookie after the header has been printed, and it's too late for cookies.

I use the later approach when I have to deal with long, complicated code, where I can't tell which paths contain a print header and which don't - and the cookies are set and printed all over the place. (I once had to maintain a piece of code that set several cookies, at various points in the code. Sometimes I came this >< close to shooting the original author).
