To send more than one cookie, create several Set-Cookie: fields.
-Alternatively, you may concatenate the cookies together with "; " and
-send them in one field.
If you are using CGI.pm, you send cookies by providing a -cookie
argument to the header() method:
Mod_perl users can set cookies using the request object's header_out()
method:
- $r->header_out('Set-Cookie',$c);
+ $r->headers_out->set('Set-Cookie' => $c);
Internally, Cookie overloads the "" operator to call its as_string()
method when incorporated into the HTTP header. as_string() turns the
$COOKIES = `cat /usr/tmp/Cookie_stash`;
%cookies = parse CGI::Cookie($COOKIES);
+If you are in a mod_perl environment, you can save some overhead by
+passing the request object to fetch() like this:
+
+ CGI::Cookie->fetch($r);

Cookie objects have a series of accessor methods to get and set cookie
