Why will this set-cookie action not work on a NT machine?

print "Set-Cookie: $key=$value; expires=$expires; path=\; domain=$domain \n";

Set-Cookie: ProtectSessionIDAdmin=3ba0cb4207ccd42c; expires=Friday, 14-Sept-2001 16:07:43 GMT; path=; domain=.pro-hosting.co.uk;

This will work on UNIX but not on NT (Windows2000)??

How to make it work on NT (Windows2000)??

* first try to leave out the domain in your cookie line

also be sure to send a \n\n at the LAST line of your set-cookie

otherwise it won't be accepted in the browser..

OR

you could use the cookie function that is implemented in CGI module;
eg.

---->8------------------>8------------>8--------
use CGI qw(:standard);

    $cookie= $form->cookie(-name=>cartnumber',
                                  -value=>"$cart",
                                  -domain=>"me.com",
                                  -path=>"/");

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

---->8------------------>8------------>8--------

it will write a standard HTML header containt the cookie, no need to write "Content-type: text/html\n\n" at the end, the form header will write it correctly..

weversbv,

"..Why will this set-cookie action not work on a NT machine?..."

Please clarify what exact does/does not happen.

Is the cookie not set at all?? If yes, then how can you conclusively confirm that?

Does is print your cookie on the screen?

Can you please post the entire code here?
What browser are you using (IE or NS or both)?

That will help you get a more accurate answer, faster.

"..How to make it work on NT (Windows2000)?? ."

Here is a teeny tiny script that you can try on your Win* box.

To confirm if the cookie is being set properly, remember to enable "Warn before setting cookie" option in your browser.

Let me know how this script works for you.
============set_cookie.pl
$DOMAIN=".somehost.com";

##  Set a Domain Cookie with no expiration date.
print "Set-Cookie: back=yes; domain=$DOMAIN; path=/; \n";

print "Content-type: text/html\n\n";
print "<h2> Cookie has been set!!</H2>\n";

You put backslash instead of slash. should be "path=/;"

you should put a slash for the path, like path=/ or path=/dir/
also, if the Set-Cookie is the last header line sent before html, make sure that you have \n\n at the end of the line

In most of the case you'll leave it path=/ , this means that the browser must send the cookie when requesting
any file located anywhere in the directory structure of your website. if this cookie is used only for administration
purposes, for example, you're using this to login an admin account to the content management system, you can
put in the path only the location of the protected directory, for example, path=/admin/

If you want to change the expiration date, the best choice is to first delete the cookie, by setting it's value to '' (empty)
and then reset it from the scratch with the new exp. date.
