There are 2 things to be aware of when using print $q->redirect(-uri=>"home.pl", -cookie=>$cookie); as pointed out in the CGI documentation under Generating_a_redirection_header.

1) You should always use full URLs (including the http: or ftp: part) in redirection requests. Relative URLs will not work correctly.
2) All names arguments recognized by header() are also recognized by redirect(). However, most HTTP headers, including those generated by -cookie and -target, are ignored by the browser.

I take from those 2 comments that the results could be unpredictable.
