primus has asked for the wisdom of the Perl Monks concerning the following question:


salutations monks,

i am working with cookies, and i am getting thrown off by placing a cookie. the documentation says: 
print $query->header(-cookie => $cookie);

[download]
though i am confused, because if you are working with a webpage, then you have to print out "Content-type:text/html\n\n" right? so if you do: 
print "Content-type:text/html\n\n";

$query = CGI->new();

# cookie stuff

print $query->header(-cookie => $cookie);

[download]
it just prints the cookie to the browser... but if i switch, or get rid of the print "Content-type:text/html\n\n"; then it works fine... and i missing something simple here?

thanks for bearing with me monks

    Printing \n\n at the end of one of your headers tells the browser that you've finished sending headers so the line printed to the browser by your $query->header(); call will be interpreted as content.

    As long as you're using the CGI header method anyway, why not just let it handle the content type with -type => 'text/html', e.g.:

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

    The header method in the CGI module returns the content-type header. If no argument is supplied then the content type defaults to text/html, so

    print $query->header()

    would do exactly the same as your

    print "Content-type:text/html\n\n";

    If you include other arguments (such as -cookie => $cookie) then these are included in the return header as well.
